Frank Bullitt's car is a 1968 Ford Mustang 390 GT 2+2 Fastback.
Filming the famous chase sequence took three weeks & lasted 10 minutes & 53 screen seconds! They were denied permission to film on the Golden Gate Bridge but did have unprecedented access to other parts of San Francisco.
McQueen made a point of keeping his head near the open car window throughout the chase so that audiences would be reassured that it was he & not a stunt man, who was driving.
Bullitt's reverse burnout during the chase scene & featured on this design wasn't scripted, McQueen mistakenly missed a turn!
MAX MUMBLES says: " Steve McQueen an actor who raced or a racer who acted?”
