I read a while back that there was a chance that Arrow and The Flash could guest star on Gotham. Anyone hear anything about that?
Personally I would like to see a crossover with The Americans on FX.
Wow that would be awful. Bruce younger than Roy? That’d make my head hurt.
It’s much more likely there could be crossovers with CBS’s planned Supergirl show, since CBS owns part of CW, and while there have been exceptions, networks like to keep crossovers in the family.
