High up on the rumor mill, there is a source that says the 'Supergirl' cast may have been leaked. As promised, Supergirl.tv is committed to report all the news we hear big or small, so we present the newest rumored cast. It starts with a young actress named Madison Riley. Madison has done some minor roles, but this is sometimes a prerequisite to do a big Superhero title. Her bio on IMDB: "Madison Riley was born on March 16, 1990 in Salt Lake City, Utah, USA as Madison Riley. She is an actress, known for Grown Ups (2010), Fired Up! (2009) and Without a Paddle: Nature's Calling (2009)". The source also revealed who may play James Olsen and Kara's Sister Alexandra.
There are some rumors that the first wave of the main cast was leaked. Correspondingly, the roles will be cast as followed: James Olson: William Shanks - He is pretty much unknown. This would be his TV-Debut Kara Zor-El aka Kara Danvers: Madison Riley - She had some little roles. But this would be her first major role Alexandra “Alex” Danvers: Mariah Buzolin - She also had some screen time. But this would be her first big role on TV I don't know if this rumors turn out to be true. But I think with this cast the series could be great.
I'm not going to put much stock in this rumor, but I do like how the cast looks if this were true. I'd like to pay a special thank you to Michael McDonnell of our facebook page who brought this news to me. Source of the article can be found here.
