One of my favourite movies from the 80s is **”Trading Places”** from **1983** with **Eddie Murphy and Dan Aykroyd**. I watch it at least once a year, usually around Christmas :o) In the first scene Billy Ray Valentine/Eddie Murphy is pretending to be disabled. The cops however know his trick already. The scene was recorded at Rittenhouse square at the corner of S 18th Street and Locust Street in downtown Philadelphia.
