Leiner's credits also included Dude, Where's My Car? and several stints in TV including Felicity, Freaks and Geeks, Party of Five, Gilmore Girls, Arrested Development, The Sopranos, and The Office.
Ross Putnam, who worked with Leiner on several projects, confirmed the news on Facebook and spoke about his friend, saying, "If there's one thing I can say about Danny the professional, it's that he refused to let us settle for anything less than our best. He pushed us to do what he knew we were capable of. Danny the person was sardonic, sharp, and savvy, with a love for culture and comedy of all kinds. It hasn't really sunk in yet, but the world has lost a good one."
Leiner is survived by his mother Anne Leiner, sister Karen Leiner, brother Ken Leiner, and ex-wife Margaret Mendelson.
