While playing pool, Patrick and Tim conceive a plan to place a tracking device on the shark, follow it in their scuba gear, and feed it dynamite hidden inside a pig carcass.

Tim and Patrick visit a shrine erected in Georgie's honor on the beach, and together mourn their friend's death by composing a song.

With the tracking device in place, Tim and Patrick pursue the shark into the bayou and kill it by tricking it into eating the bomb.

Tommy Wiseau, who used to live in Louisiana, related he was inspired to create Big Shark following the flooding of New Orleans caused by Hurricane Katrina in 2005.

Big Shark had its world pre-premiere on April 2, 2023 at Cinema 21 in Portland, Oregon,[15] before it started a limited roadshow release at Prytania Theatres at Canal Place in New Orleans on April 28 and 29, the Balboa Theatre in San Francisco on May 5 and 6, and August 5, the Landmark Westwood in Los Angeles on June 2 and 3 and July 29, the Reading Cinemas Grossmont in San Diego on July 7 and 8, and the Village East by Angelika in New York City on August 10, 11, 12, and 13.

[11] After three years of delays from its original planned release, Big Shark would finally receive its UK premiere and a limited three day run at the Prince Charles Cinema in September 2023.

Wiseau announced that the "final cut" would premiere at the Cinema 21 in Portland, Oregon, the same theater that hosted the film's world pre-premiere, on March 16, 2024.

There was debate over whether Big Shark managed to recapture the cult success of Wiseau's earlier 2003 movie, The Room.

It's straight-up Citizen Kane... despite being even more incoherent and baffling than its predecessor, it seems obvious that Big Shark has no reach beyond Wiseau's already devoted fanbase.

[38]Ariana Bindman writing for SFGATE related, "I'd be lying if I said I didn't enjoy the audacity of Big Shark."

noting "Big Shark was practically made for live audience interaction, piggybacking off the arthouse longevity of The Room screenings.

The Room has corny music and bad ADR, so Big Shark has no score and uses only live sound.
