AceShowbiz - Babylon 5 star Bruce Boxleitner has stepped in to replace Brent Spiner in TV's Supergirl after a scheduling conflict forced the Star Trek favourite to pull out.

Spiner had recently signed on to portray Vice President Baker, opposite former Wonder Woman star Lynda Carter's President Olivia Marsdin, in the show, but he has since had to withdraw from the role after filming dates clashed with a family matter.

I am THRILLED to announce I'll be joining the "Supergirl" team in Season 4 as Vice President Baker. -BB #Supergirl #SupergirlTV #CW #WarnerBros #DCComics #VicePresident #VP
