Yes, Duke Mitchell and Sammy Petrillo were attempting to ripoff Dean Martin and Jerry Lewis. Lewis had to take Petrillo to court to make him stop the impersonation (Interesting to note, Lewis was copying black vaudevillian Jimmy Cross' act himself and becoming famous for it, while Cross' race would hold him back). Mitchell is no Martin, but if I had to choose listening to either one, I would choose Mitchell over Martin's crooning. I thought Mitchell had much more life in his singing.
Other than that, had I been Jerry Lewis and I had seen a guy who looked this much like me, I would have signed him up immediately. Petrillo is so strong at resembling Lewis, they could have been boggling portraying twin brothers in a movie, but as the egotistical rift tore between Martin and Lewis, you could just imagine how Petrillo would have gone at it with Lewis. In some scenes, you can see Petrillo is masking animosity as comedy. From beginning to end the only thing that held my attention was 'That's not Jerry Lewis from the telethons.' If Mitchell had bore a resemblance to Martin, the illusion may have been even more convincing. Muriel Landers was a welcome, a rotund woman who is flirtatious and pursuing while not being threatening, something virtually unseen even today in film and television. Not a film to see for entertainment, but to just study and contemplate what is and isn't popular. Lewis was famous, Petrillo wasn't. See if you can tell the difference.
