Herve Attia has a YouTube page with several videos showcasing filming locations of many iconic movies. He cleverly split-screens and superimposes scenes from the movie with present day shots filmed from similar angles.
Herve also occasionally puts himself into the original scenes, or superimposes the original actors into the new films. His work with Ferris Bueller's Day Off and Back to the Future are two of my favorites of his works.
He recently released his latest project, revisiting the scenes from Bullitt. Herve uses a new Mustang GT to retrace most of the famous chase scene from the movie, plus some other scenes. If you're a fan of the film, I think you'll enjoy it.
