It looks like James Corden makes a brief cameo in Star Wars: The Last Jedi while trying to be a hero 🙂 This happens in the first sequence while the Resistance takes out the Dreadnaught.

Thank The Maker! According to Pablo Hidalgo this is Jamie Christopher and not James Corden.
I think that James Corden is looking unusually handsome in this sequence!
