Some actors go to extreme lengths in order to prepare themselves for upcoming roles, and Jeremy Strong is no different.

The stage and screen method actor -- whose titles include "The Big Short” and “Molly’s Game,” among others -- held nothing back to prep for his role in the Netflix film “The Trial of the Chicago 7," according to director Aaron Sorkin.

“Jeremy begged me to spray him with real tear gas,” Sorkin told Vanity Fair of the film, which tells the story of "what was intended to be a peaceful protest at the 1968 Democratic National Convention" that "turned into a violent clash with police and the National Guard," per the movie's synopsis.
