SNL skit inspired movie opening this weekend

(NBC) - A Saturday Night Live skit gets the feature treatment and the final chapter in the Shrek movie series open in theaters this weekend.

SNL's Will Forte tries to save the world in "MacGruber."

The parody of a certain 1980s TV show finds Forte forgoing firearms in favor of cunning and half-wits, as he battles an evil arms dealer.

Dieter, played by Val Kilmer, has stolen a nuclear warhead and plans to set it off in the U.S.

It's up to MacGruber and his team played by Kristen Wiig and Ryan Phillippe, to find the nuke and defeat the enemy all with their bare hands.

"MacGruber" is rated R.

It's one of those be-careful-what-you-wish-for situations in "Shrek Forever After."

This final chapter of the Shrek series finds the ogre, voiced by Mike Myers, bored with domestic life.

He makes a deal with Rumplestiltskin to restore his roar, but finds himself tricked into an alternate reality where nobody knows who he is and Rumplestiltskin is king.

It's up to Shrek undo the contract, reclaim his true love Fiona and bring order back to Far Faraway.

"Shrek Forever After" is rated PG.
