Always wanted to hear Judi Dench break down the plot of “Big Momma’s House” but never thought you’d see the day? Well friends, the wait is over.

“It’s about a little black man pretending to be a fat black lady,” exclaims Dench in the first trailer for the forthcoming Stephen Frears effort “Philomena.” It’s a pisser of a line in what otherwise looks to be one of the most tear-jerking films this year, a small-scale drama that follows Dench’s title character as she tracks down the adult son she was forced to give up for adoption decades before with the help of an unemployed journalist (Steve Coogan). Co-written by Coogan and Jeff Pope, the film won the award for Best Screenplay at this year’s Venice Film Festival and nabbed the People’s Choice Award Runner-Up prize in Toronto.

Check out the full trailer below.
