When those foreign-born actors change their names

It is a common thing for actors to change their names. There are many different reasons for it. Some are just not very pretty names, some are hard to pronounce, etc. Some, however, were of foreign extraction and had names that did not translate very well into the American landscape. Take, for example Cornel Wilde. He was born Kornél Lajos Weisz in Hungary in 1912.
