LOWELL — It’s not every day you see antique cars and dozens of people who look like they took a time machine from the 1920s.

But that was the scene Monday as a piece of downtown Lowell was transformed into a movie set.

Parts of Middle Street were straight out of the early 1900s — with a few old-school cars on the cobblestone street, and actors and actresses dressed like they were heading to a Roaring ’20s party.

The organizers were tight-lipped about the film, but The Sun learned that they were shooting scenes for “Professor Marston & The Wonder Women,” which is due for release next year.

The following is the movie’s plot summary, according to the Internet Movie Database (IMDb): “It details the unconventional life of Dr. William Marston, the Harvard psychologist and inventor who helped invent the modern lie-detector test and created Wonder Woman in 1941.

“Marston was in a polyamorous relationship with his wife Elizabeth, a psychologist and inventor in her own right, and Olive Byrne, a former student who became an academic. This relationship was key to the creation of Wonder Woman, as Elizabeth and Olive’s feminist ideals were ingrained in the character from her creation.”

The movie will focus on how Marston dealt with the controversy surrounding Wonder Woman’s creation.

Sony acquired the rights to the independent feature that stars Luke Evans, Rebecca Hall and Bella Heathcote.

It’s written and directed by Angela Robinson.
