The movie, which has been filming in Pittsburgh since July 29, moved to Heinz Field on Saturday morning, where fans were played by thousands of extras. The players returned to practice Saturday afternoon.
Roethlisberger is friends with Thomas Tull, the film's executive producer who joined the Steelers' ownership in 2009. Tull advocated Pittsburgh as a location and the Steelers' involvement in the third installment of the "Batman" trilogy, which is being directed by Christopher Nolan. Christian Bale returns as Batman and Anne Hathaway plays Catwoman.
"It's not like we're chasing Batman down or anything," Roethlisberger told the Post-Gazette. "It's something neat -- that in 10 years or 20 years we can tell our kids we were in a movie. Thomas does movies big, and I'm sure it will be a big-time movie and something fun to be part of."
