We’re getting two very different Ryan Reynolds this summer. One wearing a CG superhero suit in Green Lantern and the other swapping bodies with Ryan Reynolds in The Change-Up. Now the red band trailer for the latter has arrived, which sets out to prove this is something a little more grown-up than Big or Freaky Friday. Reynolds plays a single slacker who been best friend with Jason Bateman’s upright family man since they were kids. However after they somehow swap bodies (which seems to involve pissing in a fountain for some reason), all he breaks loose. The script by Hangover writers Jon Lucas & Scott Moore promises to delve into the area that previous bdy swap comedies have feared to tread – after all, if you swap bodies with you married best friend, are you now allowed to have sex with his wife? The movie hits Uk cinemas August 5th. Click below to watch the trailer, while you can take a gander at the brand new poster above (thanks to Moviefone).
