'The Founder' Trailer: Michael Keaton Is the King of Fast Food

"McDonald's can be the new American church."

In The Founder, Michael Keaton stars as a man with a big idea about burgers.

The trailer for the Weinstein Co. movie, which debuted online on Thursday, shows Keaton as Ray Kroc — milkshakes-machine salesman turned McDonald's founder. 

"McDonald's can be the new American church," Kroc says to small-town restaurant-owning brothers, played by Nick Offerman and John Carroll Lynch.

As McDonald's evolves into a nationwide chain, Kroc becomes power hungry with the expansion of his french fry empire, clashing with his business partners and his wife (played by Laura Dern). 

The John Hancock-directed biopic hits theaters on Aug 5.
