Here’s a look at 15 unforgettable performances, both stellar and cringeworthy, that have left a lasting mark on audiences.

15. Tommy Wiseau – The Room (Bad Acting)
Tommy Wiseau’s portrayal in The Room is infamous for its awkwardness. His line delivery feels unnatural, and emotional moments come across as hollow.

Despite its flaws, the film endures as a case study in what not to do on screen.
