Danny Masterson is an American actor best known for his role as Steven Hyde on the TV sitcom That '70s Show, which aired from 1998 to 2006. His portrayal of Steven Hyde, the show's resident tough guy, was one of the key roles throughout the entire series. Masterson's career launched significantly with this role, and he appeared in all eight seasons of the show.

Beyond That '70s Show, Masterson appeared in other television shows and movies, including Cybill, Men at Work, and The Ranch. He was also involved in Scientology and related activities.

However, Danny Masterson's later life has been marred by serious legal issues. In 2023, he was convicted of raping two women in 2003 and was sentenced to 30 years to life in prison. The case received significant attention due to his celebrity status and his affiliation with the Church of Scientology, which was reported to have interfered with the legal process.

His criminal convictions have affected his career and public image, including him being excluded from the sequel series That '90s Show, where his character was not mentioned.
