When the 52 Americans held hostage inside the US embassy in Tehran were released in 1981, they agreed to not sue Iran for damages in a US court.
But the survivors of the ordeal have taken a new tack to receive compensation for what they went through - and the latest effort has been spurred on by the Oscar-winning film Argo.
Senator Johnny Isakson of Georgia has put forward a bill that would create a surcharge on the fines levied against US companies doing business with Iran against embargo. It aims to compensate each former hostage $10,000 (£6,600) per day - more than $4m per person.
