Welcome to a new series here at Cinematical where we'll shine a spotlight on different films premiering at the 2010 Sundance Film Festival in January.

Starring John C. Reilly, Marisa Tomei, Jonah Hill and Catherine Keener, the Duplass Brothers (Jay and Mark) will return to the Sundance Film Festival yet again this year with what is definitely their most "star-studded" cast yet. The low-budget boys who first hit Sundance with a short film they made for three bucks (the cost of a tape) have since stormed the fest (as writer-directors) with their first feature, The Puffy Chair, and its follow-up, Baghead.

This year the boys will find their latest baby backed by Fox Searchlight in the Premieres section of Sundance, and out of competition. In an effort to learn a little more about the buzzed-about film (presumably due in theaters at some point in 2010), Cinematical asked co-writer/director Mark Duplass three questions about the movie, its cast and the festival itself.

Update: Fox Searchlight has confirmed that the title of the film is indeed Cyrus.

Cinematical: Give us the "dude on the street" description of your film

Mark Duplass: A divorced, lonely guy meets the woman of his dreams... she's funny, smart, hot, fun... all he can think is "what the hell is she doing with me?" Then, he meets her son. It stars John Reilly, Marisa Tomei, Jonah Hill, and Catherine Keener. They are really, really awesome in the movie and make us look like better filmmakers than we really are.
Cinematical: What was the biggest difference between working with your friends and now working with bigger Hollywood actors? Did they have to adjust to you or did you have to adjust to them?

Mark Duplass: Luckily, our "Hollywood" actors were really into our indie process. We trashed the script, improvised, found new things on the day... it was grueling and fun and totally rewarding in the end. The only major difference was that we actually had someone serving us food this time and when we went home we had real beds to sleep in instead of huddling up on the floor of some shitty apartment in our sleeping bags.

Cinematical: What non-film thing do you look forward to at Sundance every year?

Mark Duplass: Making grandiose plans to learn how to snowboard and never following up on them 'cos we'd rather be eating free happy hour food. Mango chutney/chicken skewers galore, baby!

This Is John -- Proving that you don't have to be a millionaire to make entertaining films, the Duplass Brothers conceived and shot this short on the real cheap for about three bucks and subsequently scored their Sundance debut.
