Is there any reference as to how old the Dude is in The Big Lebowski? Looks 45ish but I was wondering if there is any reference to it in the movie.
The character of Jeff Lebowski is said to be based on Jeff Dowd who was a member of the anti-war radical group the Seattle Liberation Front.
Dowd was born November 20, 1949.
At the beginning of the movie you can see the speech of George Bush "This will not stand, this aggression against Kuwait." which was on Aug. 5, 1990.
So I would say he was 40.
