Peter Dinklage is an incredible actor, and he has three Emmys to prove it. He's best known as Game of Thrones' Tyrion Lannister, but he's showing his range by stepping into a starring role in the HBO movie My Dinner with Herve, which got its official trailer on Monday. In the film, Dinklage is doing his "Philip Seymour Hoffman in Capote" transformation into a real person: in this case, into actor Herve Villechaize, star of The Man with the Golden Gun and Fantasy Island, whose tragic final days the movie dramatizes.

Dinklage does an incredible recreation of Villechaize's distinctive accent and goes HAM on the Caligulan excess of Villechaize's sad life. The movie is built around an interview the movie's writer-director Sacha Gervasi conducted with Villechaize in the days before his suicide in 1993. Fifty Shades of Grey's Jamie Dornan plays a fictionalized journalist named Danny Tate, who grows close to Villechaize ahead of his death. It's a personal project for both Gervasi and Dinklage, the latter of whom helped develop the script and who has spent his career advocating for better depiction of dwarfs in media, largely by only taking serious roles.

The movie also stars Oona Chaplin, Mireille Enos and Andy Garcia, who plays Villechaize's Fantasy Island co-star Ricardo Montalban.

My Dinner with Herve premieres Monday, Oct. 20 at 8/7c on HBO.
