STARS ACTING ODDLY

SOME OF THE top moments from Sunday’s MTV Movie Awards:

Amy Schumer channels Katniss Everdeen. Schumer put on her “Hunger Games” best, picked up a bow and arrow — which she claimed to have trained with for five hours — and “killed” Jimmy Kimmel.

Vin Diesel sings. The “Fast and Furious” star (r.) broke into song while presenting the award for Best Female Performance. “The last time I stood on this stage I was with my little brother Pablo,” said Diesel, commemorating his late co-star, Paul Walker, before belting out a rendition of “See You Again” by Wiz Khalifa, which plays in the memorial video that ends “Furious 7.”

Jimmy Kimmel roasts Kevin

Hart. Hart, who recently hosted the Justin Bieber roast on Comedy Central, got a taste of his own funny medicine when Kimmel fired jokes at the “Get Hard” actor while presenting him with the award for Comedic Genius.

“They said Kevin Hart was too small to be a comedy giant … they called him names like Eddie Smurfy, Tracy Munchkin, Cedric the Entertiny and Bernie Mac Nugget,” roared Kimmel.

Zac Efron grabs Dave Franco’s

crotch . Picking up their award for Best Duo, the actors dressed as Robert De Niro characters from “Meet the Fockers” and “Taxi Driver,” reenacting the “Neighbors” scene where their characters throw a De Niro-themed party.
