Principal photography on Jan de Bont's $40m action thriller Stopping Power has had to be suspended after the default of a key equity investor in the film made it impossible for the Internationalmedia Group to close the required financing.

The investor's breach has led to the IM Internationalmedia wholly-ownd subsidiary IM Stopping Power GmbH having to file for insolvency.

In a press communique, IM Internationalmedia stated that 'the ramifications of the insolvency on other companies in the Internationalmedia Group' were 'currently under investigation.'

The company added that it was also looking 'for alternative investors and assumes that production can be continued shortly.'

The film, which is being handled internationally by IM Global and was set to star John Cusack, Melissa George and Jason Isaacs, had been due to begin shooting in the east German state of Sachsen-Anhalt from Weds, Sept 5.
