Amanda Seyfried will star opposite Channing Tatum in an adaptation of Nicholas Sparks' "Dear John."

Adapted by Jamie Linden and set to be directed by Lasse Hallstrom, the Relativity-financed film will begin shooting in mid-October in South Carolina, according to Variety. Screen Gems will distribute.

Seyfried will play a conservative college student who falls for a soldier (Tatum) on leave. Sounds simple and romantic, right? Don't worry, since this is Nicholas Sparks, tearjerking and complications aplenty will ensue.

After toplining "Mamma Mia!," which has become an international box office sensation (over $415 million worldwide to date), Seyfried shot the Diablo Cody-scripted "Jennifer's Body." She's currently shooting the third season of HBO's "Big Love."
