Which one did you see first?
I saw the original first. I went into the video store asking for Scarface and they told me they only had the 1932 version. I took it. The most interesting thing about the movie was that it starred a family friend, George Raft. I tell people all the time when Scarface comes up, that a friend of the family, George Raft, played Tony's best friend.
When I saw the remake I liked it. I didn't like it as much as the original Scarface, but I thought it was great. Paul Muni wasn't Italian and Al Pacino wasn't Cuban, but they both did a good job. There's a funny thing that the actors that played Tony's best friends in the movies have in common. In the 1932 Scarface, George Raft was the only Italian and in the 1983 Scarface Steven Bauer was the only Cuban.
