Downton Abbey star Rob James-Collier will be donning a $6,200 (£4,000) wig for the upcoming fourth season of the hit period drama after shaving his head for another job.

The 36-year-old actor reveals he had to lop off his long, dark locks for a very different role to portray a "crazy psychotic drug dealer", so he's having to rely on stylists' help to recreate his slicked-back look as gay under-butler Thomas Barrow on the British Tv series.

He tells, "It's the king of wigs. It cost about £4,000. As wigs go, it's beautiful. And it means if I ever go bald, I can stick the wig on so I'll always have work."

Production on the fourth season of Downton Abbey began earlier this year (13) and is due to air in the U.K. this autumn (13).
