Nick Zano (one big happy, what i like about you, 2 broke girls, Happy Endings) to co-star as Pre-cog Arthur.
In the movie, Dash and Arthur were identical twins, played by identical twin brothers. The identical twins premise was carried over to the pilot, with one actor, Sands, cast to play both roles. (Arthur does not appear in the pilot beyond a blurred image at the end.) Now that concept has changed, with Dash and Arthur becoming fraternal twins with distinctly different personalities played by two different actors, Sands and Zano.
The show has already cast Stark Sands as Dash and Meagan Good as Lara Vega (the detective).
