Christopher Hemsworth (born 11 August 1983) is an Australian actor, notable for roles in Snow White and the Huntsman, the 2016 version of Ghostbusters, Men in Black: International and as the Marvel Cinematic Universe Thor.
In "Baby Stewie", Stewie's gene altering device operation manual is filled with images of him with Chris Hemsworth haircuts. When Brian tries to use the device to turn Stewie back into his normal self after he becomes a regular baby, the computer tries to prompt him to select a Chris Hemsworth haircut and shows a live-action picture of Chris as Thor.
When Stewie suggests a movie could be made of his and Doug's adventure in "80's Guy", Chris is cast as Stewie's, played by Paul Giamatti, thought bubble girlfriend.
Stewie tunes out Lois by listening to the audiobook Times We've Been Nude by all three Hemsworth brothers in "Prescription Heroine".
