Steven Soderbergh's martial arts action flick, Knockout, has just added a series of impressive names to its cast.

Channing Tatum, Michael Douglas, Michael Fassbender, Ewan McGregor and Dennis Quaid will join first-time actress, and mixed martial arts expert Gina Carano in the film that will predominately shoot in Ireland and Spain. According to The Hollywood Reporter, the flick is budgeted at $25 million, which means that the impressive cast are most likely working for scale as a favour to Soderbergh. Tatum will apparently train with a Mossad agent in preparation for the part.

Soderbergh is shooting here as he wants to make the most out of his low budget, and we still offer solid tax incentives. Really looking forward to seeing what the Oscar winning director will do with his first out-and-out action film. Also, there may be a considerable amount of star spotting to do in the next couple of months by the sounds of it.
