The first American film to use the word "c***sucker".
A half-hour television pilot based on this film aired on ABC in 1979 as Where's Poppa? (1979), but the series was never picked up.
During what was probably Rob Reiner's big breakout scene in a film, his then wife Penny Marshall was an extra, sitting in the first row of the courtroom, almost looking like she was silently cheering him on. Rob's father and Penny's father in law, Carl Reiner, was directing the film.
Included among the American Film Institute's 2000 list of the 500 movies nominated for the Top 100 Funniest American Movies.
