A talent agent is suing Larry Hagman's estate over allegations he is owed money for managing the actor's career.

John Castonia claims he agreed a contract with Hagman after the actor signed up to appear in the Dallas relaunch, but the star died just three months into the $2,500 (£1,471) a week agreement.

Castonia, who claims the contract was for a minimum of seven months, is now suing the estate to recoup the cash he claims he is owed, according to Tmz.com.

He is asking for $42,500 (£25,000).
