Lindsay Dunlap has a message for Warner Bros. and Matthew Vaughn: Don’t mess with “The Man From U.N.C.L.E.”

Dunlap’s Ember Entertainment holds the underlying rights to the 1960s cult TV series, bought from the show’s original producer, Norman Felton, in October 2003.

Warner has an option to make a movie version, which it inherited from Ted Turner long before Dunlap got involved.

Vaughn, who made his helming debut with “Layer Cake” for Sony, has agreed to direct, although he has yet to sign his deal. He’s in talks with writer John Hodge to reinvent the spy caper for a 21st century audience.

Vaughn recently told Variety that their ideas for the project were “like nothing you’ve ever seen before. The name is the only thing that’s staying.”

According to Dunlap, those comments prompted a flurry of outrage from die-hard “U.N.C.L.E.” fans.

“We don’t need to go into legalities, but I just want anyone who takes this on to know that we’re watching closely,” per Dunlap. “If anyone attempts to just use the title, the fan base will not turn out to see this film, which will be commercially damaging.”
