Paranormal thriller "The Last Word" has begun filming here in Shreveport. Stars of the film include Mike DoyleErin Cummings and Sean Patrick Flanery.

The movie is based on the true story of 17-year-old Johnny Frank Garrett. The mentally-challenged Texas teen was convicted and sentenced for the rape, mutilation and murder of a 76-year-old nun. Garrett claimed his innocence up until his dying breath.

Sixteen years later, new evidence popped up suggesting Garrett was wrongfully executed.

Peter Facinelli website

Another well-known name in this movie is Peter Facinelli, who's listed as one of the producers. You might remember him as Dr. Carlisle Cullen from the Twilight saga, and from his role on the TV show Nurse Jackie, but I know his best as jock-bully Mike Dexter in Can't Hardly Wait.

He was also formerly married to Beverly Hills 90210 (the first go-round) star Jennie Garth. The two were officially divorced earlier this year.

According to his website, he's "excited to be teaming up with Film District to produce" the film. Its anticipated release date is summer of 2014.

If you're wondering where the filming is taking place, we do know that there's some going on around Fairfield Avenue, between Dalzell and Boulevard in the Highland neighborhood. Traffic will be interrupted in that area from 9 a.m. until 9 p.m. Thursday.
