I've seen the film many times...I don't get the reference.
Anyhoo, OP:
The 45* rule of thumb may be for general riding with elbows slightly bent, sort of in cruising mode. If you want to get more aero you want to bend those elbows more, or get on the drops and bend those elbows to get the torso more horizontal. TT angle has little to do with either scenario.
