Solving the Puzzles

Rating: 7/10 (22 February 2002)

This film draws parallel to the classic Sunset Blvd. Both Sunset and Mulholland are street names and Rita/Camilla never actually find where is she trying to go but stumbled into a house on Sunset Blvd. Both films tell a story about a once beautiful Hollywood actress with a tragic ending.
Major spoiler********** I have only seen it once, there are so much detail that I didnt catch but here is what I think.
I think the homeless person (the detective saw in his dreams and died from a heart attack) is actually Rita/Camilla after the car accident that she not only lost her memory but she got disfigured as well. Remember how the moment after the car accident, there is a smoke covered scene? That scene repeats itself towards the very end where the grossly disfigured person walk out from it.
Notice how the singing audition and the movie sets are actually of the 50's? This is the hint that the actual event (reality) happened during that time. When the homeless Rita/Camilla picked up the blue box from the dead detective, the box unlock her memory, so the entire movie is actually about the flash back some 50 or 40 years ago.
