The Grandmaster Cameo
Jeff Goldblum will forever go down in history as being an acting sensation and a meme, and we say this in the kindest way possible. The actor who was made famous in a relatively unknown film about dinosaurs (/s) also got to start in multiple MCU films. You know him as The Grandmaster from 2017’s Ragnarok, but he also made a brief appearance in GOTG Vol. 2.
Technically, his first MCU role was his cameo appearance in the end credits of Vol. 2 since it came out several months before Thor: Ragnarok. When asked why Jeff was in Vol. 2 at all, James Gunn claimed that they were filming the Thor movie nearby, so why not?
