The Paul Webb-scripted project takes its name from the Alabama town that witnessed a historic civil rights march in 1965. Jackman is expected to play state governor George Wallace, a role that previously interested Robert De Niro.
"I had to do a lot of homework on the script, and I spent a lot of time writing. I feel like I'm caught up a little bit with that," Daniels said. "I have to really start casting the movie because we're shooting it soon. The only person I've nailed in for sure is Hugh Jackman. It's all over the place."
Selma is due to begin production in May, reports USA Today.
