I have best acting skills but I want to know more about height.

There isn't one. Robert Downey Jr. And Michael J Fox are both very short. Usually short guys get put on Apple boxes or in platform shoes to be of comparable height to any taller costars so height isn't a factor in casting.

Not sure what the arbitrarily minimum height would but but some of the top men in Hollywood are pretty short, such as Tom Cruise and Robert Downey Junior.
