A romantic comedy, "I Fine, Thank You, Love You", the latest film from GTH, grossed 29.17 million baht in ticket sales on its opening day - the second-highest ever for a Thai movie.
According to the film's Facebook page, it surpassed the 21-million-baht mark set by Pee Mak Phra Khanong, a 2013 comedy horror film directed by Banjong Pisanthankul and also produced by GTH.
I Fine, Thank You, Love You hit cinemas nationwide on Wednesday, Dec 10. It was directed by Mez Tharatorn, who had big success with ATM Er Rak Error, also a romantic comedy.
Action star Tony Jaa's most successful action flick Ong Bak, released in 2003 by Sahamongkol Film still holds the biggest opening day ticket sales at about 30 million baht.
The plot of I Fine, Thank You, Love You centres on a teacher, Pleng, who is asked by a Japanese student leaving for the United States to tell her boyfriend Yim she wants to break up with him.
Yim then blames Pleng for perfecting his girlfriend's English skills and nags her to teach him to speak English, so that he too can go to the US and get his girl back.
The tutor initially does not want to teach Yim, a factory worker, but she later agrees to help him. As the English lessons continue the two start to learn about each other and gradually fall in love.
Leading cast members of this film include Sunny Suwanmethanon, Preechaya "Ice" Pongthananikorn and Japanese adult video star Sora Aoi.
When pronounced with a "Thai" accent, "I fine" comes out as "Ai fai" and means "you're a buffalo" in trendy Thai jargon.
