Ok, on the surface it's just a four-digit number. But are there shared thematic links between the two films? Scroll down for more.
Seconds, John Frankenheimer (1966)
2046, Wong Kar-wai (2004)
In Seconds, 2046 is the train Arthur Hamilton (John Randolph) takes from Grand Central Station back to his safe home in the suburbs. An aging businessman who let life pass him by, he's given an opportunity to begin anew, thereby escaping both his present and his past, though for a price.
In 2046, a mysterious train, the creation of writer Chow Mo Wan (Tony Leung), leaves for 2046 "every once in a while." Chow longs to escape from the pain of a failed romance. He creates a future world set in 2046, where escape is an impossibility, and lost memories are captured.
Seconds: "Is it easier to go forward when you know you can't go back? ... Fact is, you don't want to go back."
2046: "Everyone who goes to 2046 has the same intention, they want to recapture lost memories. Because in 2046 nothing ever changes. But, nobody knows if that is true or not because no-one has ever come back."
Trains, temporal escape, and you can't go home again. Valid connections, or am I just straining for ideas at 2:30 in the morning?
