Actor Jeff Corey would also appear years later on Newhart (Tickets, Please).
Bob, Emily, Carol, and Scott discuss a movie titled "Big Al" starring Ryan O'Neal as gangster Al Capone. This was pure fiction and no such movie exists.
The title is based on the song Old Man River from the musical Showboat with music by Jerome Kern and book and lyrics by Oscar Hammerstein II. The original production opened on Broadway in 1927 and was a milestone in the musical theater.
