It's either a show or a movie based entirely on Clayface, specifically the two-part episodes from Batman: The Animated Series about the very handsome actor who was aging out of the business, and ended up in debt to the mafia and couldn't pay them back, so they drowned/suffocated him in the cream he was using to stay young looking: https://www.youtube.com/watch?v=6IxPD-jNdwM

The trailer doesn't look bad, but seeing that the show/movie will be indulging in niggertry makes it a no-go for me.
