Shia LaBeouf has had his ups and downs in recent months — and it's being reflected in his latest performance art piece.

LaBeouf, along with musical collaborators Nastja Sade Rönkkö and Luke Turner, are livestreaming their experience for 24 hours in a cramped elevator in Oxford, England. The trio started the project Friday morning — using the hashtag #ELEVATE — and will end it at 9 a.m. local time Saturday.

LaBeouf is allowed to take bathroom breaks, and will also step outside temporarily to host a talk Friday night at the debating society at Oxford University.

Visitors have been sharing their experiences on the elevator with the 29-year-old "Transformers" star, who is answering questions and taking selfies.

Shia does not like Harrison Ford, Donald Trump. Loves Bernie. “It would be great if he were President.” #ELEVATE — Daniel Dalton (@wordsbydan) February 19, 2016

Our conversations with Shia LeBouf was apparently very dark compared to everyone else. That's about right. #ELEVATE pic.twitter.com/eZDwbW75Mx — Scott Bolohan (@scottbolohan) February 19, 2016

@NikoCoromelas it's symbolic. Being in a small enclosed space...It can only take you up or down...people coming and going... #ELEVATE — Dana Khuribet (@Dana_Kh) February 19, 2016

LaBeouf is no stranger to bizarre stunts. Last November, he sat in a New York City movie theater to binge-watch all 29 of his films as part of his #ALLMYMOVIES project.

The following month, LaBeouf, Rönkkö and Turner staged a phone-a-thon in which they asked callers to "touch their souls."
