This afternoon a Boyhood Bluray was left on my doormat, and tonight there’s a cool-sounding Boyhood party at a certain old-world location. Director Richard Linklater and costars Ethan Hawke, Patricia Arquette and Ellar Coltraine will attend. The official inviters are Diane Keaton, John Hamm, Frank Marshall, Sean Daniel, Jack Black and Julie Delpy. I always laugh when the person who initially sent the invite writes back to say that (a) rsvps are through the roof and that (b) you therefore might want to come a little bit later (it’s a four-hour event) and (c) if you’re thinking of not attending to please let us know. The 2-disc Paramount Home Video release popped yesterday.
