I may be wrong about one or two on the list in terms of origination format, but out of 36 titles, 12 were shot on film -- so 33%... But that's ignoring, for no particularly good reason, the larger production market as if all of those indie features and TV series that used to shoot film somehow don't count.
But I don't think you can say this is still a "reasonable amount" considering all the labs that closed down and the fact that Fuji got out of the motion picture business and Kodak has killed a number of their stocks (and I think Kodak now just has one sales rep working out of house since Kodak closed their offices in Los Angeles -- the "capital" of the movie industry!) There are now whole regions of the world, let alone the U.S., where it is hard to get movie film processed. There's no way to put a positive spin on this, film is in serious decline.
I'm shooting film right now because the director insisted on it and she doesn't have to justify that decision to anyone, she got her own funding. That's really the only way film is being shot on features, by directors who insist on it and have some control over the budgeting process.
