The memorable "Aaaugh!" scream from
Peter Robbins as Charlie Brown originated from this film. (Oddly enough, it was also heard from Linus in one scene.) Robbins' scream would become a stock sound effect in almost all subsequent Peanuts specials & movies up to the late 1990s, and is used as a scream, not only for Charlie Brown, but any other available character (excluding Snoopy and Woodstock, who had their own variants).
