Peter Dinklage is Tyrion Lannister in Game of Thrones
Contrary to many of the other actors Game of Thrones made stars of, Peter Dinklage already had an accomplished career in the world of acting, although his showbiz beginnings began in the world of music with the group Whizzy.
His acting debut was in 1995 with the film Living in Oblivion, then followed by Elf, The Station Agent, The Chronicles of Narnia: Prince Caspian, and Penelope, among others. After the first season of Game of Thrones we saw him as Bolivar Trask in X-Men: Days of Future Past and as Eitri in Avengers: Infinity War.
