There was a time not too long ago when if you asked me what my favorite movie was I might have told you Mulholland Drive. There's a lot going on in the film and I certainly won't claim to understand all of it (something I might have done when it was my "favorite movie"), but I do have a reading of it that seems to answer a lot of the questions it poses, so here goes. No specific spoilers (hence no spoiler tag), but if you haven't seen Mulholland Drive you really ought to see it as blind as possible.
The first half of the film is, for lack of a better term, Naomi Watts's dream (the first shot after the jitterbug stuff even approximates a head laying down on a pillow). It is her fantasy of the world as she wants it to be. If you compare it to the second half (her reality), you can see the way she refashions the people in her life to fit her desires for them. Here's a few examples:
Laura Harring (Rita/Camilla): In reality, Naomi Watts wants her but can't have her, so in the dream she becomes an amnesiac (a blank slate for Watts to project her desires onto) who can only remember Naomi Watts's name (her real life name "Diane", not her fantasy name "Betty"). Watts's character is literally the only thing in her life.
Justin Theroux (Adam Kesher): In reality, he's engaged to Laura Harring, making Watts jealous and angry (he seems to flaunt their sexuality in front of her). In the dream, Watts makes him into this impotent, petty, bumbling version of himself (he's still a director, but he's not allowed to cast his movie the way he wants, and his girlfriend cheats on him, and he's generally shown to be a pawn controlled by the mafia, the cowboy, etc.—essentially, she takes away his agency).
Melissa George ("Camilla" in the dream): In reality, she's a close friend of Harring (Watts sees them kissing), so in the dream Watts's jealousy turns her into an actress who only gets work because the mafia force Theroux to accept her.
Mark Pellegrino (Joe Messing the assassin): In reality, he's a hitman hired by Watts to kill Harring. She regrets this decision (seen in the way she looks at the key which signifies the job is done), so in the dream he becomes a fool who spends his time with hookers and accidentally kills more people than he intended to (one of the film's funniest scenes).
Much more than being a simple "it was all a dream" twist, the film's dual nature offers us insight into the relationship between fantasy (our frame for understanding the world around us) and fiction (in this case, cinema). Everything about the first half of the movie is self-consciously theatrical. The performances are obvious, the lighting is overdone, and the story is filled with overused tropes and cliches (e.g. police detectives, a case of mistaken identity, etc.). The first half is like a movie being created in Naomi Watts's mind. It's obvious that movies are essentially fantasmatic (whether they're constructed from the fantasies of the author or as fantasies for the audience), but Mulholland Drive offers us the opposite truth: that these fictions come to determine our fantasies. That the way we understand the world is by filtering it through the fantasies offered to us in the world of fiction. That we give meaning and purpose to our chaotic lives by understanding them as a narrative. That (as Lacan says) truth has the structure of a fiction.
- When Naomi Watts (as Batty Elms) calls the number for Diane Selwyn, she says, "It's strange, calling yourself." What's interesting about this line is that she is actually calling herself (her real name is Diane Selwyn and we hear the voicemail message again in the second half of the film when Watts is at home in reality), but she doesn't know that yet—she thinks she's calling Laura Harring (as Rita).
- When Naomi Watts and Laura Harring go to club Silencio (still in the dream/fantasy), Rebekah Del Rio sings a song called "Llorando" which accurately describes the couple's relationship in reality (translated: "I love you even more / than I did before / but darling what can I do / for you don't love me / and I'll always be / crying over you"). It's appropriate then that the song is sung in Spanish (Watts's attempt to cover up her trauma); however, it still seems to hit too close to home, because it's after this moment that Watts decides to use the key (which in reality signifies Harring's death) and we transition to the second half of the film (the "real" half).
- When The Cowboy talks to Justin Theroux, he says, "You will see me one more time if you do good. You will see me two more times if you do bad." We never see The Cowboy meeting with Theroux again, but he does make two more appearances (once to wake up Watts in the transition to the second half and once in the background of Justin Theroux's party), which leads me to believe that he's referring to Watts as having "done bad" in the sense that she is responsible for Harring's death. (Bonus: The Cowboy seems to be an echo of Lost Highway's Mystery Man since not only are they both eyebrow-less characters, they are both embodiments of guilt. Both characters serve as reminders of the protagonist's evil deeds, as if they are superego incarnate.)
- David Lynch originally planned for Mulholland Drive to be a TV series, and he famously struggled with ABC to the point that when he lost support for the project he initially rejected funding to turn the pilot into a feature film. These conflicts with producers give a new level of meaning to the scenes with Justin Theroux's producers, particularly when they shut down his movie in petty retribution for a single casting disagreement (coincidentally, ABC rejected the pilot in part because Watts and Harring were "too old to be TV stars"). Of course, while these scenes are bitingly satirical of the production system, Lynch also resists the temptation to lay all the blame in the hands of executives, and Theroux's character (the director) appears just as petty and childish as everyone else.
- I love Justin Theroux in this movie more than I can explain.
- I love "Sixteen Reasons" in this movie more than I can explain
- I love that the story of the dream in the diner happens exactly the way Dan describes it right after he tells Herb about it (Dan sees Herb where he says he saw him in the dream, etc.).
- I love how when Naomi Watts imagines/hallucinates Laura Harring in the reality segment of the film there's a traditional shot-reverse-shot (Watts to Harring back to Watts), but then there's an incredibly jarring cut from Watts back to Watts where we expect another shot of Harring. So unsettling.
I love that Billy Ray Cyrus blames Mulholland Drive for the way his daughter Miley turned out.
- The ending of the film hit me harder this time than it ever has. Maybe that's the effect of seeing it in a theater, or maybe it's just that I'm older now, or maybe it's the fact that I'm babysitting my parents' cats and they wake us up unreasonably early and I haven't had a good night's sleep all week.
