The Danish parent company of financier Liberty Production has cut off funding, citing the present international economic crisis.
The film's producers are now seeking support from Finnish capital investors and patriotic circles. Producer Markus Selin says that over three million euros have already been spent on the movie.
"It would be a catastrophe if filming would have to be delayed, "said Selin.
The film's director, Renny Harlin, said Friday that he hopes that the present situation is only temporary. He added that it is annoying that the production has been put on hold now that all the arrangements for filming have been made and spirits are high among actors and crew.
Filming of "Mannerheim" was scheduled to start next month in Joensuu. The production company, Solar Films, is to make a decision next week about when shooting will begin.
Carl Gustaf Emil Mannerheim is an iconic figure in Finnish history. During his career, he was an officer in the Imperial Russian Army, the commander of the winning White forces in the Finnish civil war, Finland's commander-in-chief during WW II and President 1944-46.
