The Big Bang Theory star Kunal Nayyar is facing legal action from a talent agency over allegations he failed to keep up with commission payments.

The actor was allegedly looked after by staff at Diverse Talent Group when he landed the job in 2007, and has paid a percentage of his wages in commission in subsequent years.

However, in a suit filed at Los Angeles County Superior Court last week (ends25Nov12), lawyers for the company claim Nayyar stopped making payments last September (11), and allege they are owed $100,000 (£62,500), according to Tmz.com.
