This quick documentary gives some pretty interesting insights into the making of Bullitt, which I found to be especially interesting because so much of the film was shot not only on location, but on very difficult locations. Steve McQueen is something of a stuntman in real life, given his extensive interests in motorcycle and car racing, so naturally he wanted to do as many of his own stunts as possible, and I think that kind of dedication really comes across in the film. When stuntmen are used in movies there are so many times when you can just tell, even if you can't really see their faces, and I think it takes away from the movies as a whole.
There is also a lot of interesting footage of the cast and crew working on location, behind the scenes, and this DVD includes some pretty interesting information about the research that some actors did in preparation for their roles, such as riding along with SFPD officers to learn how they worked, as well as using real doctors and nurses in the hospital scenes. Overall an interesting documentary, and definitely worth the ten minutes it will take to watch it!
