There is a Marx Brothers movie (Love Happy, 1949), where Harpo escapes some villains chasing him atop the 4-position neon sign... One of the villains was Raymond Burr (later Chief Ironside in the famous TV series).
Not their best movie, but if for historical reasons you want to see Marylin Monroe's first movie scene, this is the one to watch...
Ciao from Massimo
Thanks, Massimo, good info! I am a huge Marx Brother's fan, although I haven't seen one of their movies in years. That scene with Harpo seems to trigger my memory, but it was so long ago, and my memory isn't what it was. I will try to find Love Happy and enjoy it again.
As for Raymond Burr, he had an even more famous role as Perry Mason, but, I did not know about that being Marylin Monroe's first movie. Or, if I ever did know, it's long forgotten.
