The Bond movies might be an exception, though they didn't start until 1962 (I'm not including the '55 TV movie of Casino Royale).
Seriously, though: Do we really need a sequel to a movie that came out 28 years ago? I know the shadow of nostalgia is longer and wider thanks to home video, the Internet, "expanded universe" merchandise, etc., but seriously, this is ridiculous and reveals the emptiness and absurdity of this kind of relentless franchising. (I dunno if "moviemaking" really even counts as a word anymore, since the actual movie is basically ancillary to all the other crap used to promote it.)
Lemme put it this way: 28 years before 1984 was 1956. What movies from 1956 did anyone want to see or make a sequel to in 1984?
Is anybody thinking of picking up a PS Vita? Five or ten years ago, my early-adopter antennae would be positively quivering at the prospect, but today... meh. The notion of buying a dedicated gaming handheld just seems weirdly quaint to me. (And the fact that Sony doesn't appear to have learned from its mistakes marketing the PSP in the States doesn't fill me with enthusiasm.)
It's always fun to hear composers reuse bits of music from earlier scores. James Horner used to do this all the time before he became famous, and Leonard Rosenman recycled a lot of his score from Bakshi's LotR for Star Trek IV.
Most famously, John Barry took the "love theme" from the Italian B-movie space opera Star Crash and reused it seven years later as the main theme for Out of Africa. He won an Oscar for it. Johnny Greenwood had a right to be pissed off about his There Will Be Blood score being disqualified.

Later they switched to old people's medicine, which was not only commonplace, but greatly more energy efficient.
