Here is Peter Mayhew as Chewbacca in Star Wars:
Here is Peter Dinklage as Tyrian in Game of Thrones:
While there is some passing similarity (besides the name) — perhaps in the way they groom their hair, or maybe a bit in the way they walk.
But Peter Mayhew is 7’3″. Peter Dinklage is 4’5″.
Maybe I should get a tape measure.
Anyone with a worse mixup?
