E! has secured a rare four-year window of exclusive TV rights to Knocked Up.

The cable channel paid $40m to NBC Universal Domestic Television Distribution for a package of rights that also includes Evan Almighty and I Now Pronounce You Chuck and Larry.

Some of the films will go for their first TV runs on NBC properties such as USA; however, many - including Evan Almighty - is exclusive to E! until 2013.

Variety reports that E1's rights also extend to other Comcast-owned channels such as the male-skewing G4.
