star Angus T Jones looked in his first TV appearance for seven years.
The 30-year-old, who on the family sitcom, has returned to acting with a cameo appearance in comedy series Bookie, which debuted on Max on November 30.
His last acting role, after leaving Two and a Half Men in 2013, was an episode of a 2016 web series created by Louis C.K. called Horace and Pete.
In Bookie, Angus reunites with his Two and a Half Men co-star Charlie Sheen, 58, and showrunner Chuck Lorre.
The show follows a veteran bookie struggling to survive the impending legalisation of sports gambling, increasingly unstable clients, family and co-workers.
The pair’s scene will thrill Two and a Half Men fans with a major easter egg as it recreates the series’ iconic pilot when Jake is watching his uncle Charlie Harper (Charlie Sheen) play poker with his friends.
Both Angus, who looks unrecognisable with a beard 11 years after leaving the CBS programme, and Charlie play themselves in Bookie.
Angus played Jake in Two and a Half Men, with Jon Cryer playing his father Alan Harper, from 2003 until 2013.
In 2010, Angus became the highest-paid child star in television at the age of 17 when his pocketed him $7.8 million (£6.1 million) over the next two seasons, amounting to US$300,000 (£236,000) for each of the 26 episodes.
However, when his character was given more adult storylines in 2011, where Jake was portrayed as a heavy marijuana user and sexually active, Angus said he was not comfortable with the scenes and that it had been ‘very awkward’ to do them while he was not legally an adult himself.
The following year he shared that he had turned towards religion, becoming a Seventh-day Adventist, and soon after called the show ‘filth’ and no longer wanted to appear as it conflicted with his faith.
In a 2012 YouTube video, he said: ‘You cannot be a true God-fearing person and be on a television show like that. I know I can’t.
‘I’m not OK with what I’m learning, what the Bible says and being on that television show.’
However, he later issued a public apology, saying he was ‘blessed’ to have worked on the show.
But two years later he doubled down on his initial statements and said the sitcom was ‘making light of topics in our world that are really problems for a lot of people’.
While he has nearly 25,000 followers on Instagram, he rarely shares any updates on social media and largely retreated from the spotlight after leaving Two and a Half Men.
