Hi Tony, just saw the movie this week. The titles you mention are obviously not the type in the picture above.
The titles were on screen too short to have a real good look, but the details (except for the straight legs of the M) looked like Futura: a narrow E and L, a B with a wider lower bowl, a wide pointed N in Berlin; the elegant S, and a R with a bit of a thigh gap between its legs. Also, some non-american texts were subtitled in what looked like Futura. I think the titles are based on Futura, but adapted.
These Futura's are not unlike the titles in the movie: Futura No. 2 and Paratype Futura.
If you are looking for something with a straight legged M, you could have a look at Battling and VF Sans.
