Will Ferrell has topped a list of luminaries whose returns offer the least value for money.

According to Forbes' list, the movie funnyman made just $3.29 (£1.97) for every dollar he was paid after a run of box office disappointments.

Ewan McGregor finished second, followed by Billy Bob Thornton, Eddie Murphy and rapper turned actor Ice Cube.

Forbes calculated stars' estimated earnings against the performance of their films to devise their list.

The only female star to make it into the top 10 was Drew Barrymore at seven, whose average return amounted to $7.43 (£4.46).

Last month, Forbes published a list of the actresses who give the best value for money, in which Australian star Naomi Watts came out on top.
