LONDON ? Reports that Joseph Fiennes is set to play Michael Jackson in an upcoming drama have been flying about social media recently, and Twitter really doesn't know what to make of it. Fiennes will star as Jackson in a one-off drama about an unusual road trip the singer is rumoured to have taken with Elizabeth Taylor and Marlon Brando in the aftermath of the 9/11 attacks, the Guardian reports. The casting choice has prompted some fairly strong reactions on Twitter. Some people didn't believe it.
