Released in 2013, Justice League: The Flashpoint Paradox is an animated film.
As indicated in the title, this focuses on the Flash as it crosses into an alternative reality.
Barry Allen/The Flash is played here by Justin Chambers and Chambers plays Alex Karev in Grey’s Anatomy.
Chambers’ Grey’s Anatomy co-star Kevin McKidd is also here and he plays Thomas Wayne who in the reality that The Flash visits is Batman instead of his son Bruce.
The one casting that caught my attention is Dana Delany reprising Lois Lane whom she played before in an animated Superman series.
Disappointing she had very little to do here as she is one of my favourite women.
Also includes brief appearances of familiar elements including the Joker.
This movie is very dark, viewing that is more suitable to an adult audience as it looks at the paradox in question and its darkness is not quite to my taste.
