In celebration of the Friday nationwide theatrical release of “50/50″, starring Joseph Gordon-Levitt and Seth Rogen, two videos of cast roundtable interviews have been released. The roundtables include Rogen and Gordon-Levitt, as well as fellow cast members Bryce Dallas Howard, Anna Kendrick and writer Will Reiser. The two-part interviews include conversations about the making of the film, which was based on the real life story of Reiser and Rogen’s friendship throughout Reiser’s battle with cancer. Also a restricted clip, “Evidence,” has been released. All three clips are below the post.

Here’s the synopsis of “50/50″:

“Inspired by a true story, 50/50 is an original story about friendship, love, survival and finding humor in unlikely places. Joseph Gordon-Levitt and Seth Rogen star as best friends whose lives are changed by a cancer diagnosis in this new comedy directed by Jonathan Levine from a script by Will Reiser. 50/50 is the story of a guy’s transformative and, yes, sometimes funny journey to health – drawing its emotional core from Will Reiser’s own experience with cancer and reminding us that friendship and love, no matter what bizarre turns they take, are the greatest healers.”
