I am looking for the font of the film Limitless (2011).

I know the font it's pretty famous, at least many kinds of sources with the same characteristics, but the font of the film in particular has features like a small ondulation in the letter "R" of the Bradley Cooper name (see poster) or a lineal wave of the letter "S".

The following fonts are similar, but they are NOT:
DIN 1451
Lane E
Lowvetica
Media Gothic
OldSans
Eurostile (varieties)
Microgramma (varieties)
Nimbus Sans Extended Regular Std Web

I've been looking at official sale webpages, but there are so many fonts it's impossible to locate it.

Thanks in advance.

As this post is old, you might have found your answer, but I think I found one that is almost the same: AG Book Extended BQ. The only problem is this font looks like it's not free.
