Jeff Goldblum’s delivery, hesitant, self-interrupting, apparently improvised, is so distinctive that it has become the thing he is hired for. It was already fully formed in The Big Chill and The Fly.
The Fly is the performance that proves the rest. Playing a man disintegrating physically over ninety minutes, he keeps the character funny and articulate until he cannot be, and the film works because the audience liked him first.
Independence Day and Jurassic Park made him a blockbuster fixture, and his Ian Malcolm is the delivery given a mathematics degree.
The late career, in Thor: Ragnarok and Wes Anderson’s films, has leaned fully into the persona, and he has become a public figure somewhat separate from the work.
