Supergirl director Craig Gillespie has spoken about how DC Studios head James Gunn had given him free reign with directing the new DCU movie. However, it turns out that he did have some notes on one particular character: Krypto.
The super-dog featured heavily in Superman and is a huge part of Supergirl too as it follows Kara Zor-El having to go to extreme lengths to save her four-legged best friend. After he's poisoned by the evil Krem, she ends up teaming up with a young girl named Ruthye to find the antidote to save him.
