It's good to be Brie Larson. She's got a busy plate of movies ahead of her, is coming off '21 Jump Street' and has been added to the already stellar cast of Joseph Gordon-Levitt's 'Don Jon's Addiction.' There she'll be playing Gordon-Levitt's sister.

She'll be joining Julianne Moore, Scarlett Johansson and Tony Danza in a film about - as Variety tells us - "a porn-addicted, modern day Don Juan (Gordon-Levitt) who sets out to become a less selfish person after meeting a recently widowed older woman (Moore)." From what Variety is reporting it looks like it's close to wrapping, which means Larson's part is relatively small.

But of more interest is that they suggest she's already signed on for  the '21 Jump Street' sequel, which has yet to be announced. 'Jump Street' made $138 Million domestically, and just hit DVD and Blu-ray, where it should also perform strong (international numbers are generally weak on comedies, this is no exception). With the first film's directors Chris Miller and Phillip Lord working on their 'Lego' movie, and with Channing Tatum having a huge hit with the autobiographical 'Magic Mike' it seems like now would be the time to start moving forward on that project.
