Yea, my group is currently playing in a 1920 - 1930's campaign. We have a couple popular culture figures in our game.
We have one person playing Doc Brown the mad scientist.
Another person playing a fraudulent Alan Quartermain.
One's Playing a reporter named Stoned Deaf.
Another is playing a meat head boxer named Crusher O'Brien
Then of course we have my character Patrick O'Connell who is an Irish Mobster.
So far it's been a lot of fun, we're ending our current adventure within the next couple sessions and hopefully starting the next campaign by march. I sort of have a blog site coming up that deals with a lot of our stories along with some audio caption of some of the games. I'll get a link up when i get more stuff added.
