One of the FBI agents is named Special Agent Leonard Heisman. The father of Mark Harmon (who himself played football at UCLA) was a Heisman trophy winner as a tailback for the University of Michigan.
Lucas asks Marcy to have ballistics tests done on a cartridge that hasn't been fired. There will be no marks from grooves, no firing pin mark and no extractor marks. All they should be able to do is possibly determine the brand.
By the time the narration mentions that Lucas is driving on I-35 (which should be I-94 - see under Errors in Geography), he is already off the interstate roads and traveling on local highways.
In the final garage escape scene when Harmon shoots at the Jaguar on two levels of the garage, the same scene is used twice. (Look for black truck backed in.)
