The license plate is close, but not the one on Burt's trailer http://justacarguy.blogspot.com/2010/02/burts-trailer-simple-and-effective.html , and the tall guy is wearing new sneakers, nothing looked like those in the 60's, and Burt was skinny
It's a good movie, and incredible that it's the first for the (writer, director, producer, set director, music, editor) do it all - Faith Granger

I didn't want to watch the silent film, not once I learned that a anime version with English vocals was made. It's a magnificent epic story that varies a lot from the original, and I recommend it highly. The original was written about on Wikipedia, and seems to be a very difficult story to follow, and that must be why it was editted differently by anyone who could, resulting in every known copy that existed from the 1930's to the 1990's having about 30 minutes cut from it to make the story cohesive. Watch the anime version for enjoyment, or the original if you're a film afficianado. http://www.imdb.com/title/tt0293416/ 

Sounds like a Richard Pryor swearfest, but it's got Checker cabs throughout, car chases, good guys becoming a team and facing the bad guys, solving a kidnapping, and overcoming adversity.
