+1 For Blues Brothers but I can't decide which chase
That was amazing, I LOL'd at the end. Thanks for sharing, Scutter!
<<<<< The Grand Daddy of all chases, Steve McQueen's Bullitt.
I don't know about "Best" but my two most memorable ones are the mall chase in The Blues Brothers and the final chase scene in the original Gone in 60 Seconds.
