The Screen Actors Guild has ordered the closing of the production of Nailed in South Carolina.
From Deadline Hollywood Daily:

I’m told by knowledgeable sources that David O. Russell’s indie political comedy Nailed which began filming in April was shut down by the Screen Actors Guild on Friday because of insufficient funds on deposit with the guild. I’ve also learned the Columbia, S.C. shoot is in trouble with both IATSE and Teamsters, and some of those union members have left the beleaguered $25 million budgeted production. Rumors also are circulating that the state of South Carolina could withdraw its incentive monies because of the financing problems. Filmmakers hope to resolve the cash crunch and re-start shooting next week since principal photography is only at the halfway point. “I am confident we will finish,” an insider on the pic just told me. “The financing on this like most indies is based on bank loans and bridge loans. This is a matter of waiting on the bridge loan. Hopefully, it will all be resolved.”
