The YouTube video font for the credits looks a lot like Times NR, or some Times version.

And it apparently is. I never thought it might be about THE most commonly used font nowadays. Sorry for the inconvenience.

Any idea about the poster one?

I was looking at that one and had trouble finding that M from BATMAN. The lettering at the top of the page looks like Futura Condensed Bold, but that is not the same as the BATMAN lettering.

I think the "BATMAN" logo may be a custom job. Warp Three from Nick's Fonts is close.

Thanks a lot!
