To get you started on this dreaded Monday:

Natalie Portman is putting out her own stoner comedy. Pajiba reports that the actress is searching for a director for the upcoming Best Buds, which she will star in and produce with her company Handsome Charlie Films. The film is being compared to the likes of Harold and Kumar and Half-Baked, and will focus on two best friends who road trip to another friend's wedding "in order to save her by bringing her weed." Can Portman pull off an Anna Faris? In fact, will Faris sign on to play the other friend?

While Portman gets high, Leonardo DiCaprio is still loving the thriller world. Deadline Hollywood reports that the actor is interested in Prisoners, a film that, just last year, had Bryan Singer directing Christian Bale and Mark Wahlberg. DiCaprio is looking to play "a small-town carpenter who takes matters into his own hands when his daughter and her friend are kidnapped." It's a Black List script, which suggests good things, but it should be a while before we hear more. Deadline hears that he'll probably make another film before he gets to Prisoners.

Meanwhile...

Coming Soon has spotted that Green Lantern's director Geoff Johns has confirmed the Sinestro casting on Twitter: "Mark Strong is going to be a brilliant Sinestro."

Hall Pass, the Farrelly Brothers' film, has grabbed Stephen Merchant and J.B. Smoove to work alongside Owen Wilson, Jason Sudeikis, and Jenna Fischer. They'll play friends of Wilson and Sudeikis' characters in the film about a married man who's allowed to have an affair. (THR)
