What Airplane is This?

I was watching TCM the other night and they had a Rock Hudson movie that I had never before seen. It was shot in the mid-50's and featured a number of great classic airplanes. There were two identical low-wing monoplanes. I have attached a movie poster showing the white version of the plane. Can anyone here identify this plane?

Thanks,

Curt
