It looks as if the Weinstein Company has delayed the releases of both Anton Corbijn's Control and Grant Gee's doc Joy Division until June. There's some dispute among the seller sites, but the date of 10 June looks to be more likely. You may have noticed, too, that IFC/Genius have also delayed Christophe Honoré's Dans Paris, with Romain Duris and Louis Garrel, until 6 May. Again, there is some dispute with this film's release.
Also, ThinkFilm, who appears to now be owned by Image Entertainment, will push Paul Schrader's The Walker from April to 27 May. Despite what you may have heard, it's actually quite good. ThinkFilm/Image will also be releasing The Air I Breathe, with Sarah Michelle Gellar, Brendan Fraser, Julie Delpy, Andy Garcia, Forest Whitaker and Kevin Bacon, in May.
