Amanda Seyfried & Thomas Sadoski's Chemistry Was Clear on 'The Last Word' Set

Amanda Seyfried and Thomas Sadoski‘s chemistry has been obvious since the beginning!

The couple, who are now engaged with a baby on the way, had intense chemistry on the set of The Last Word, according to the film’s director Mark Pellington.

“This natural, real chemistry emerged on camera. It was like, ‘Boy, there’s something there’ – more than playing their roles. It was like, she seems really into him. And he seems really into her,” Mark explained.

He added, “The connection and the chemistry worked off-camera too. Obviously.”
