In documents filed by the Oscar nominee, obtained by The Hollywood Reporter, Keitel claims he signed a deal with E*Trade to feature in three commercials for the firm.

However, he alleges E*Trade bosses later told him the campaign was "moving in a different direction" and offered him a $150,000 (£93,750) termination fee.

In the lawsuit, the actor's legal team argues, "By offering a 'kill fee,' E*Trade acknowledged and admitted that it had an existing, binding and enforceable contract with Mr. Keitel."

The Pulp Fiction star is requesting the full $1.5 million plus interest.
