Alejandro Gonzalez Inarritu’s Birdman, or the Unexpected Virtue of Ignorance (Fox Searchlight, 10.17) will open the Venice Film Festival on Wednesday, 8.27. Which gives Inarritu and his cast (Michael Keaton, Zach Galifianakis, Edward Norton, Andrea Riseborough, Amy Ryan, Emma Stone, Naomi Watts) enough time to fly to the Telluride Film Festival for screenings beginning…oh, let’s make it Saturday, 8.30, so as not to jam them too hard. They probably won’t make the picnic but no worries. Venice runs from 8.27 through 9.6. Telluride runs from 8.29 to 9.1. And the Toronto Film Festival — sloppy Birdman thirds, guys, but them’s the breaks — is from 9.4 to 9.14.
