Magnum: Gilbert Roland

I know most people are thinking Clark Gable, but I have to go with Gilbert Roland. If you’re familiar with his films, you know he did action, drama, romance, had a knack for comedy and he was damn good-looking too!
Higgins: Claude Rains

Watch Casablanca and you’ll know why. He was such a versatile actor. He would have made a great Higgy-Baby IMHO.
Rick:

I can’t make up my mind. I’m thinking either George Raft or James Cagney.
TC: Rex Ingram

I’ve chosen Rex Ingram. To round out the main cast.
Agatha: Elsa Lanchester

Yes, Elsa was the Bride of Frankenstein, but in her other roles she excelled at being scatter-brained comic relief.
Carol: Eve Arden

Eve was often referred to as “Comedy Insurance” when cast in a film. Always the bridesmaid, never the bride, she would have made a great Carol.
Mac: Bob Hope

Pun intended, but I l know what you’re thinking. Don’t think of 1980’s Bob Hope – the elderly Bob hosting a prime-time special on NBC with Brooke Shields. Think of the Bob Hope from the “Road” films with Bing Crosby.
Doc Ibold: William Powell

This was an easy decision. Powell was great as Doc in the 1955 film Mister Roberts, a very similar role.
Ice Pick: Edward G Robinson

I can’t think of a better local crime boss. He can be mean as hell, or a sweetheart. He perfected the role.
J Digger Doyle: Lauren Bacall

Many of the leading ladies of the golden-era were either over-the-top glamour queens or not very athletic in nature. Lauren was different.
So, who would be your choices? I’ll be adding characters to this thread as I think of more…
