You are correct. Those were the ONLY remakes I could think of off the top of my head.
Didn’t know The Maltese Falcon was a remake.
Never saw the original Ben Hur.
I like Silents, so have seen many of them ( starting in my childhood ) on T.V. and at the MUSEUM OF MODERN ART in NYC.
The original film of A STAR IS BORN, was tiled: "WHAT PRICE HOLLYWOOD". It's the same plot, the same characters, just a different title. All tolled, there have been FOUR remakes, all called A STAR IS BORN, and the ONLY great one is the first remake!
The original THE WOMEN also was remade and remade and RE MADE to death with the original film ( which was just an adaptation of the ORIGINAL BROADWAY PLAY ), the ONLY good one.
The original GASLIGHT was a Brit film.
Usually, ALL remakes can't hold a candle to the original film and that sometimes holds true for the TALKIE remakes of the SILENT ones.
While not much of a movie watcher for about 41 years, the Ben Hur with Heston had some well acted moments, such as the scene where Ben Hur is rowing in the Roman warship, and the scene with Stephen Boyd’s fatally injured ‘Messala’ (while in agony) telling Ben Hur his mother and sister have leprosy.
