Downey said on social media, "It's been 40 years since I was last on 'the boards,' but hopefully I'll knock the dust off quick.

'McNeal' is a timely and important story about the future of creatives, and I intend to do it justice." In the play, Downey portrays Jacob McNeal, described as "one of our greatest" writers and a "perpetual candidate for the Nobel Prize in Literature." The synopsis states, "McNeal also has an estranged son, a new novel, old axes to grind, and an unhealthy fascination with artificial intelligence.
