The Congress is a film based on Stanislaw Lem’s novel The Futurological Congress. I say based, because the plot of the book, as given by Amazon, and the synopsis of the film share similar themes, but that’s about it:
Robin Wright, playing the role of herself, gets an offer from a major studio to sell her cinematic identity: she’ll be numerically scanned and sampled so that her alias can be used with no restrictions in all kinds of Hollywood films – even the most commercial ones that she previously refused. In exchange she receives loads of money, but more importantly, the studio agrees to keep her digitalized character forever young – for all eternity – in all of their films.
The contract is for 250 years and the movie is about what happens after the contract is over as Ms. Wright attempts to make her acting comeback. Apparently that involves a lot trippy, seemingly LSD-induced animated sequences that would do PKD and Richard Linklater proud. I have no idea what the #$^@$%&% is going on here, but it sure looks intriguing.
