The CRY ME A RIVER hunk is branching into acting and has been trailing PULITZER PRIZE-winning journalist BOB PORTERFIELD to research his part in EDISON.
Timberlake studied the action stars' lawsuit - against an electronics firm that used their likeness in adverts without permission - for about 45 minutes at Los Angeles's county courthouse.
ASSOCIATED PRESS journalist Porterfield says, "He was interested in learning how you retrieve these public records. Basically, I showed him how you find them, how you request them.
"I thought he was sharp. He seemed attentive and interested in learning this stuff. He has a real interest in developing his part. He took quite a few notes."
