The party starts at 7 p.m. Friday on Theatre Baton Rouge’s Main Stage, but hold on to your socks.

Because everybody’s losing them in Hedges Pictures’ newest film, “The Day of the Hedges,” made especially for the film company’s 15th anniversary celebration.

“It’s both a comedy and a mystery, and, really, it’s kind of silly,” says Travis Hedges Williams, the company’s founder and director. “But we wanted to do something fun for the celebration.”

Admission is $5 for this celebration, which starts with the world premiere screening, followed by a Masquerade Gala in the theater’s Social Room with music by Harker’s DJ Services and a cash bar.

As for the film, Williams filmed the story during a 12-day span in July. He’s billing it as a Baton Rouge version of “The Avengers,” which groups favorite characters from his past films hunting down an evil hipster whose favorite pastime is crashing parties to steal socks.

The villain is played by Ronald Coats, who’s just coming off playing multiple roles in Theatre Baton Rouge’s production of “Monty Python’s Spamalot.”

“With Ronald as the villain, you know it’s going to be funny,” Williams says. “But everyone else is funny, too. The film not only brings back viewers’ favorite characters, but their favorite actors in Hedges Films.”

The gala will give audiences a chance to meet Coats and other cast members, Abigail Tatum, Kurt Hauschild, Tyler Grezaffi and Jeffrey Johnson. Williams also acted in and directed the film. Jesse Seidule was the director of photography and Allen Calmes wrote original music for the soundtrack, performed by local band Prom Date.

“We’ll also be inducting six new members into the Hedges Pictures Hall of Fame,” Williams says. “We created the Hall of Fame for our 10th anniversary celebration, and we have 10 people in it so far. You can see the who on our Hedges Pictures (hedgespictures.com) webpage.”

The evening will also include a retrospective of Hedges Pictures’ early works. Those who aren’t able to make the premiere and party can tune in on Hedges Pictures’ website, where “The Day of the Hedges” will be posted along with the company’s complete film library.

“This is our 27th movie in 15 years,” Hedges says. “We’ve kept an insane schedule.”

All that’s left to do is keep a close eye on your socks while celebrating at the masquerade.

“The film and celebration are all in fun,” Williams says. “And we’re already planning our next film.”
