Watch the first trailer for 'My Big Fat Greek Wedding 3'

Focus Features have released the first official trailer for My Big Fat Greek Wedding 3, offering a look at the latest Portokalos party.

Star Nia Vardalos returns as Toula Portokalos in the first trailer for My Big Fat Greek Wedding 3, which she also wrote and directed. The cast also includes John Corbett, Andrea Martin, Louis Mandylor, Maria Vacratsis, Elena Kampouris, Elias Kacavas, Gia Carides, Joey Fatone and Melina Kotselou.

In the sequel, Toula mourns her dad Gus (played in previous films by actor Michael Constantine, who died in August 2021 at 94) and the family honours him by following through on his last wish: for them to visit his childhood village and "reconnect with our roots."

"So we're having a reunion. And by we, I mean the whole family," Toula says in the trailer.

Nia wrote and starred in the original hit rom-com My Big Fat Greek Wedding back in 2002 with John. There was a sequel in 2016, plus a short-lived TV series My Big Fat Greek Life in 2003.

In February, Nia told PEOPLE there was a scene in the new film in which she and Corbett "were both in tears" because of how "incredible" it was to film.

"We actually have a scene where we're dancing on a dock in the most beautiful cobalt light that our incredible cinematographer Barry Peterson waited for and waited for and waited for," she said.

"John and I are standing on a pier dancing together, and we were both in tears. It was incredible," she added. "It's just the view around, just the blue of the light, the water. And [Corbett] said, 'Baby, look where you brought us.' Isn't that amazing? And then I said, 'Thank you for coming.'"
