George Lucas didn’t leave well enough alone when he began using digital technology to “improve” the special effects in Star Wars. To the dismay of just about everybody but himself, Lucas kept tweaking until eventually he had Greedo rather than Han shooting first in the Cantina.
Alfred Hitchcock remade The Man Who Knew Too Much to get out of his contract with Paramount and/or because he thought he could do better in 1956 than he did in 1934. Either way, I’ve watched the earlier film many times, and the later one only once.
