Can anyone identify the font used in the logo of the movie “if....”? I don’t have a better sample, unfortunately. I tried attaching it, but it wouldn’t let me, so, I’ve inserted it in the post, instead.

looks a lot like ITC Tiffany Heavy, but not exactly the same.
The reason I don’t think it’s based on Tiffany is the square ends on the serifs. Tiffany has round ends on the serifs. Otherwise, I agree there is some similarity. The top of the f is very similar to Poster Bodoni (a.k.a. Ultra Bodoni), but the bracketed serifs and the top of the i are very not Bodoni. It also has some similarity to very bold Caslons, but the top of the f is not like Caslon at all.

i noticed that too, but unless he’s looking for the exact precise match (which might not exist), Tiffany is a pretty good alternative.
by the way, here’s a somewhat better look at it, where you clearly see that the serifs are square unlike Tiffany.
