Sir Sean Connery's hairstyle in this movie was based upon composer Jerry Goldsmith's well-known ponytail. Meeting him at a cocktail party, Connery started the conversation by saying, "I want your hair." Goldsmith replied, "You can't have it, it's mine." Connery, and even the producers, felt Goldsmith's "pulled back ponytail" fit the character of Robert Campbell very well.
While promoting the movie on The Tonight Show Starring Johnny Carson (1962), Sir Sean Connery stated that he would start each day playing a round of golf. He carried his own club and played at such a pace that the younger cast and crew members playing with him could not keep up.
This script became the subject of a heated bidding war when it was simply titled "The Stand."
