ET has the latest...

'The Imaginarium of Doctor Parnassus,' the TERRY GILLIAM-directed movie HEATH LEDGER was working on before he died on Tuesday, has been suspended indefinitely, according to People.

The Association of Canadian Film Craftspeople business manager tells People the suspension puts 100 crew members out of work until producers decide whether or not to scrap the movie or recast Heath's role. Ledger was reportedly due to arrive in Vancouver on Friday to continue filming.

Meanwhile, sources tell ET that Gilliam is saddened by Heath's death and that the filmmakers are hoping to regroup after the weekend and then decide how to proceed.
