WASHINGTON, Dec 20 (Reuters) - The film "Concussion," tracing a forensic pathologist's quest to expose the truth about brain injuries in the NFL, casts a spotlight on an issue that has roiled America's most popular sports league.
The movie also may give parents pause, according to the filmmakers and some former players, about allowing their sons to play the violent sport of football.
"I love football. It's graceful. We have a lot of beautiful football in this film, purposefully," said Peter Landesman, the director and writer of the movie, due in U.S. theaters on Dec.
