4) Brett Dalton
There’s only so many times that Agents of S.H.I.E.L.D. can keep bringing Brett Dalton back to the show. He’s had a good run and made a lasting impact, but it’s time to say goodbye and move onto greener (read: darker) pastures on Inhumans… LOL! Just kidding, we’re talking about him as Batman in the Arrowverse.
The 34-year-old actor is in the same age category as Stephen Amell and could act as a valuable and equal ally to the Green Arrow, rather than the creepy older guy who hangs out with younger people and bosses them around. It’s entirely plausible that this could then be the foundation for the start of the TV version of the Justice League. The Flash, Superman, and Supergirl are already present, so why not bring in the whole gang?
Furthermore, who wouldn’t want to see Dalton’s Bruce Wayne talking trash to Amell’s Oliver Queen about how he ripped off the Batcave from him? We foresee a lot of back-and-forth banter between these two that could result in riveting TV. Think about it: Marvel’s loss could be DC’s gain, so it’s in their best interests if they strike fast and tie him down to a contract.
