The first film adaptation of *Great Expectations* was in 1934, starring:
* Dickie Moore as Pip
* Florence Reed as Miss Havisham
* Basil Rathbone as Abel Magwitch
* Jane Wyatt as Estella
However, there was a very popular 1946 film adaptation of *Great Expectations* in the UK, not the USA, starring:
* John Mills as Pip
* Valerie Hobson as Estella
* Anthony Wager as Herbert Pocket
* Francis L. Sullivan as Abel Magwitch
* Alec Guinness as Herbert Pocket's father
* Martita Hunt as Miss Havisham
So, depending on which adaptation you're thinking of, the actors will be different.
