Jessica Chastain is going all in!

The first trailer for "Molly's Game," Aaron Sorkin's directorial debut, presents Chastain as Molly Bloom, a former Olympic-level skiier who ran a high-stakes, exclusive poker club for over a decade before getting caught by the FBI.

Based on Bloom's own tell-all memoir, the movie takes Molly from helping her boss run a poker room at the "Cobra Lounge" (really the Viper Room on the Sunset Strip) to creating a thriving business of her own. The money is flowing, players are happy — until Molly gets entangled with the Ruffian mob. Then, the FBI comes a-knocking and Molly hires a lawyer (Idris Elba), who advises her to name names.

The dialogue is quick and snappy, just as we're used to from Sorkin's previous work in "The Social Network" and various TV shows ("The West Wing," "Newsroom," "Sports Night"). It's interesting that Sorkin has never directed a movie before, though he was in line to helm "The Social Network" if David Fincher passed.

"God knows I was scared going into it," Sorkin told Entertainment Weekly of directing "Molly's Game," "but I just felt like if I was ever going to do it, it was going to be this."

"Molly's Game" also stars Kevin Costner, Michael Cera, Chris O'Dowd, and Brian d'Arcy James and opens in theaters November 22.
