As one of the most recognizable faces in Hollywood, actress Jennifer Aniston can be a strong advocate for many types of campaigns and causes. She recently showed her support for the awareness of Amyotrophic Lateral Sclerosis (ALS).

On Saturday, Aniston’s fiancé, actor Justin Theroux, performed the ALS ice bucket challenge and included her name as one of his nominees to take the challenge next. The ALS ice bucket challenge is a social media campaign that recently went viral, and entails people getting a bucket of ice and water poured over their heads within 24 hours of receiving the challenge or forfeiting the action by donating to ALS research. Like Theroux tagging Aniston, people must tag friends to do the challenge.

What Is ALS?

Theroux’s video of his ALS ice bucket challenge starts with The Leftovers actor talking to an unidentified friend about the setup of the challenge before he faces the camera and introduces himself. Aniston’s groom-to-be then states that he is accepting the ALS ice bucket challenge, which was given to him by Damon Lindelof, showrunner of TV series Lost, and Jason Bateman, film and TV actor.

Theroux goes on to list his nominations for taking the ALS ice bucket challenge. He includes members of the Labyrinth Theater Company in New York, one of which is actor Sam Rockwell, and adds Mulholland Drive director David Lynch.

“And because she’s not here to see me do this, Ms. Jennifer Aniston,” he concludes before the bucket of ice water is poured over his head. In the video, Theroux can be seen gasping for breath and unable to talk due to the cold, while his friends can be heard laughing in the background. Aniston must now either take a video of herself performing the challenge or make a donation to ALS research.
