Should be an easy one. The font used in the movie "Goodfellas" during the credits.

A clarification - I'm pretty sure it's the original Helvetica Bold. But with the very tight spacing common with early versions like on phototypesetting machines, that were popular in American graphic design of the 70s and 80s. You would have to apply negative spacing in order to get this tight with digital versions as they're more spaced for text use. Or buy Neue Haas Grotesk Display (a premium font) which is already spaced for this kind of display setting.

I don't think it's Helvetica Neue (at least, not the version bundled with Apple software) - the 'M' is much narrower. On here, it's roughly a square.
