Why isn't this film more well known/remembered?
I've been in an epic film mood lately, and while watching this again I showed it to my father who while a big fan of the genre (he's the one who introduced me to all of the other films I bring up in this post) and Charlton Heston as an actor had actually never seen it before. And it just got me to wondering on why this hasn't become considered a big well known classic to many up to now like "The Ten Commandments", "Ben-Hur", "Spartacus", "Lawrence of Arabia", and "Doctor Zhivago" that all came out around the same time period. (Mid 50's - Mid 60's, Hollywood's Golden Age of large scale epic films) It's strange because I thought I had heard it was a hit in theaters, it has a very famous and popular lead, and to most who I have encountered who have actually seen it (usually in the online community) seem to love it. (I and many others I have talked with about the film have all even held it in the same esteem as those other films. Even Director Martin Scorcese considers it one of his favorite films.) What's kept it so obscure? I mean even compare the number of votes all these films have gotten on IMDB, not even half (heck, not even a quarter) as many votes as any of them.
El Cid: 7,033
The Ten Commandments: 34,063
Ben-Hur: 102,124
Spartacus: 74,799
Lawrence of Arabia: 125,564
Doctor Zhivago: 45,637
I'm just curious as to what others think of this, and to speculate (unless they ouright know) why they figure this occurs. I'm just pretty disappointed with how underrated this film is.
