“Nailed” is back in production this week in Columbia after its third work union stoppage in a month, but the movie’s producer is facing lawsuits for unpaid bills and loans, a trade publication is reporting.

David Bergstein, who heads “Nailed” backer Capitol Films, has been sued by advertising promoter Allied Advertising for $4.2 million in unpaid bills, Variety reported. This month, businessman Alexander Sandel filed suit against Bergstein and five affiliated production entities over loans totaling more than $4.5 million, Variety reported.

Bergstein did not respond to Variety’s request for comment. Bergstein is expected to close a bridge financing deal soon, the publication reported.

The comedy “Nailed,” starring Jessica Biel and Jake Gyllenhaal, started shooting in mid-April around Columbia. Shooting is scheduled to end in mid-June.

The International Alliance of Theatrical & Stage Employees ordered its members last week to not show up at the set after not being paid. The same union also stopped production a couple of weeks ago after not being paid.

The Screen Actors Guild had ordered its members to walk off the film set early this month because producers failed to deposit enough money in accounts to pay actors.

Forty-six checks for the “Nailed” production bounced due to insufficient funds, according to the film’s bankers quoted by Variety.
