NBC will kick off the 40th season of Saturday Night Live Sept. 27 with Guardians of the Galaxy star Chris Pratt as host. Ariana Grande will make her SNL debut as the musical guest.

By that time, the Marvel space adventure likely will have passed the $300 million mark in the North American box office. It's already the highest-grossing film of 2014, ahead of Captain America: The Winter Soldier, The LEGO Movie, Transformers: Age of Extinction and Maleficent. To date, Guardians has earned more than $587 million worldwide.

Pratt, who's heading into the seventh and final season of NBC's Parks and Recreation, also starred this year in The LEGO Movie. He'll next be seen on the big screen in Jurassic World, opening in June 2015.

The Oct. 4 episode of SNL will feature Sarah Silverman with musical guest Maroon 5.
