Tina Sinatra offered Ray Liotta the role of Frank Sinatra but he turned it down. Liotta later played Sinatra in The Rat Pack (1998).
Philip Casnoff is convincing in the musical numbers because of his Broadway experience in musicals such as "Grease," "Chess," "Shogun, the Musical," and "Chicago". However, in spite of his theatrical background, his voice was not considered the right tone for playing Frank Sinatra. Instead, Philip lip synced to the singing voices of Australian actor Tom Burlinson and Frank Sinatra, Jr.
