I really like Henry Cavill as Superman, I loved Man of Steel - but I rewatched Superman the Movie a couple of times after Man of Steel came out and there's no comparison. I believe that if somebody wrote a half decent story for Cavill and gave him some actual lines, he'd be great. A serious Superman could work (plenty of DC's best Superman stories portray him as a very serious character e.g. Kingdom Come), but he needs a well-written story and a director who actually understands the character. Sadly, he's used as a prop more than anything else. So, he's number two.
And as for number one. Well, who else could it be ?
Christopher Reeve is the closest anyone's come to capturing everything that I believed Superman was about - sadly a couple of his films were garbage, but he was still amazing, so much so that he was the only good thing about
Superman III and Superman IV (other than the idea - that Superman would get involved in nuclear disarmament, now that's gold).
Also, Superman the movie has the worst deus ex machina ending of all time - but still Reeve manages to sell it. While Donner was a good director, he had the all-time best ever casting choice to work with.
The only good bit in Superman III is where Superman fights himself, and only Reeve could have pulled that off.
And of course, that last moment in each of Reeve's Superman films, as he flies off into the sunrise, where he smiles at the audience.....well that gets me every time, and now, nearly 40 years after I saw it as a child, it takes me straight back to seeing that film as an 8 year old, and walking out feeling like
I could fly.
BTW I love the title/question of the thread because it uses the word "favorite" it's straight up about opinion, not an invitation for debate but just a chance to sound off about our preferred option.
