Mostly as i did with Spiderman, im making a fanfic with this crossover (Spider&Bat) and having some doubts on the cast.

As i wanted a more adult and mature Batfamily, i had some good picks:

Jon Hamm as Batman Jane Levy as Batgirl Dylan o Brien as Nightwing Sam Rockwell as Joker Amanda Seyfried as Harley Ana de Armas as Catwoman

My doubts: although Sam Rockwell is almost the same age as Jon, hi doesnt look very "mature" and Willem Dafoe seems too much old (idk, ready to listen to ideas)

No problem with Margot, although she looks much a baby face and young than Amanda who i guess could pull a pretty harsh Harley villain.

Ana de Armas is my biggest gripe, having the age of Jane and Dylan, how to not be strange from she having romance with Jon? The other pick would be Rachel Weisz.

Again, out of the cast, im here to listen to you guys. My project is a fanfic yet in writting and as most fanfics, part of the fun is to build your cast. Once i finish dedice who play who, i will make images of them with costumes (by IA) to ilustrate the key part of the story. That said, the casting is important
