Justin Timberlake has signed on to join Clint Eastwood and Amy Adams in Warner Bros.' baseball drama Trouble with the Curve, which will mark the directorial debut of Clint Eastwood's longtime producing partner Robert Lorenz.

Randy Brown wrote the script, which finds Eastwood playing an aging baseball scout with vision problems who takes a road trip to Atlanta with his daughter to take a look at a hot prospect.

Justin Timberlake will play Clint Eastwood's pal Johnny Flanagan, a former pitcher who now works as a baseball scout for the New York Yankees. His character is a potential love interest for Amy Adams, who plays Clint Eastwood's daughter.

No production date has been set.
