The monthly Labor Day casting is upon us, with THR having learned that Lucas Hedges (Moonrise Kingdom), Micah Fowler, and Alexie Gilmore (World’s Greatest Dad) are signed and ready to go for Jason Reitman‘s next. The currently-shooting project stars Gattlin Griffith as Henry Wheeler, a boy looking after his desperate, dispirited mother, Adele (Kate Winslet), and whose life changes (for the better?) when an escaped convict (Josh Brolin) shacks up with them over Labor Day weekend.

Hedges will be seen as Richard, the son of Alexie‘s character, Marjorie, who’s also Henry’s stepmorth. Fowler — who, from what I can (or can’t) gather, is entirely new to film — has found himself with the role of “Barry, the son of Adele’s friend Evelyn.” James Van Der Beek, Clark Gregg, Tom Lipinski, and Brighid Fleming are co-starring in Labor Day, which will be opening sometime in 2013. A perfectly appropriate slot may have already established itself.

Afterward, it’s said that Runner, Runner will now be graced with the talents of Michael Esper. The picture’s being helmed by Brad Furman (The Lincoln Lawyer), who’s using a screenplay by Brian Koppelman & David Levien wherein a hotshot Princeton student (Justin Timberlake) ends up with a high-level position at the company he was cheated by. Esper, best known for his work on Broadway’s American Idiot, will be seen as an employee (make that tattooed employee) of this group. [Variety]

Ben Affleck, Anthony Mackie, Oliver Cooper (Project X), Gemma Arterton, Ben Schwartz (Parks and Recreation), and Sam Palladio (Episodes) also star in the film, which New Regency and 20th Century Fox will release sometime in 2013.

On a final note, Deadline has learned that Sonya Walger (Lost, Common Law) is the next actor up for Admission, a comedy that’s locked Paul Rudd, Tina Fey, and Michael Sheen as its stars. Paul Weitz will direct it all, that being the story of “an Ivy League admissions officer named Portia Nathan (Fey), whose relationship with a 17-year-old recruitment prospect threatens to unravel her personal, romantic, and professional lives.” Caren Kroner has written the screenplay, which is a take on Jean Hanff Korelitz‘s own novel. Ms. Widmore is playing Helen, a professor at (recurring theme!) Princeton.

How are these films shaping up?
