As part of Universal's Toronto International Film Festival press junket for Ron Howard's Formula 1 racing flick "Rush" (September 20), this Sunday at noon before the film's world premiere, Howard and star Chris Hemsworth will conduct their first ever Facebook Q&A. They'll also answer fan questions on the "Rush" Facebook Page.
Like many celebrities and filmmakers these days, Ron Howard is figuring out that building a fanbase online is part of his job. Here’s his Facebook page. He's following the lead of film composer Hans Zimmer (who also did the score for TIFF favorite "12 Years a Slave"), who did a Q&A Saturday for his more than 1.2 million Facebook fans.
