Entertainment Weekly reports that Ben and Kate star Echo Kellum has been cast as Curtis Holt, A.K.A. Mr. Terrific in the upcoming season of CW's Arrow. At Comic-Con International: San Diego, it was revealed the character would be joining the show but the casting wasn't announced at that time.
In comic books, Mr. Terrific is Michael Holt, a brilliant olympic athlete who becomes a hero after the death of his wife and child. In Arrow, EW describes Holt as an inventor who works for Palmer Technologies under Felicity Smoak. It was also revealed at SDCC that this version of Mr. Terrific will be gay.
The new season of Arrow debuts October 7, and Kellum is scheduled to debut in the subsequent episode.
