Alan Ladd played Jay Gatsby in the 1949 adaptation of The Great Gatsby. I haven't seen this particular version, that I recall. I haven't seen this year's adaptation either. I just can't bring myself to see a film starring Leonardo DiCaprio. He is just to swarmy for me. I have seen the 1973 and the 2000 versions and found them less than impressive. I just don't know if anyone has the acting chops to bring Gatsby to life.
