Tom Felton has lightened the mood during the final days of shooting new movie Ghosts Of The Pacific by pulling sneaky pranks on his co-stars.

The Harry Potter actor is preparing to wrap production on the upcoming adventure film, and has spent his breaks goofing around on set - much to the dismay of his fellow castmates.

He took to his Twitter.com page on Thursday (09May13) to post photos of the carnage, which began when actor Jake Abel managed to squeeze a bicycle into the cramped seat of Felton's golf cart.

The Brit tweeted, "Last days filming on Ghosts (of the) Pacific. May the pranks begin. Firstly Jake Abel thought it amusing to modify my buggy... So I thought I'd return fire with some improvements of my own, to his buggy of course. Happy driving Jake."

Felton posted a photo of Abel's electric cart decorated in blue tape, and the duo then teamed up to terrorise co-star Garret Dillahunt by covering his bike in toilet paper.

Felton adds, "Jake thought it wise to install some improvements to Garrett Dillahunt's fold up bicycle. I agreed..."
