How does a film like this expect to make a profit?
I would imagine it was the fee that attracted Ernest Borgnine to this film because it certainly wasn't the script.
The film is low budget, a large proportion of the budget will probably go towards attracting recognisable faces like Borgnine, Van Cleef and Kinski and these films are hardly successes which is not surprising.
Are these films made as some kind of tax write-off?
