Jason Clarke plays Senator Ted Kennedy in this drama that focuses on his car accident in 1969 in which Mary Jo Kopechne dies. Casts melds well. Some scenes are a bit too farcical to be believable. Could he really have had no idea of the repercussions of his decisions? Were his aides keystone cops? If anything, the movie spurred me read up on the incident to find out more. Bruce Dern's performance was spot on.
