It isn't a big surprise that director Roland Emmerich's White House Down is full of action, since this is the same filmmaker who brought us Independence Day. The latest featurette reveals how physical it got for the actors on the set, including Jason Clarke, who suffered two broken ribs and a "badly twisted ankle" while shooting fight scenes with Channing Tatum. Jamie Foxx, Joey King, writer James Vanderbilt and producer Brad Fischer also talk about how loud it would get on the set, and much more in this behind-the-scenes video.
