“Luther” star Idris Elba proposed to his girlfriend Sabrina Dhowre on Friday at a screening of his upcoming directorial debut, “Yardie.”

“Another Rio Cinema first!“ tweeted the venue, a more than 100-year-old London movie theater, on Friday. “Still 5 days to Valentines Day but @idriselba went down on one knee and proposed to his girlfriend live on stage this morning before a preview of his film #Yardie.”

The moment was captured on cellphone video shot by David Marsden, a partner at London’s Sainou Talent Agency, who posted it on Instagram with the message, “When you turn up to the #Yardie screening with @sainoutalent clients . . . and the director @idriselba steals the show with a #marriageproposal.”

The video shows Dhowre and Elba on the theater stage. She steps toward him and then leans forward, as Elba, on one knee, holds out a ring. They stand and kiss as the theater erupts in sustained cheers. Afterward, he takes a small bow toward the audience and the couple kiss again.

Neither Elba, 45, nor his representatives have commented.

The actor told People magazine in September he and Dhowre had fallen in love while shooting “The Mountain Between Us” in the area around Vancouver, where she lived. “Falling in love while making a movie about falling in love is pretty special,” Elba said. He and Dhowre made their red-carpet debut that month at film’s Toronto International Film Festival premiere, after having made their first public appearance at the festival’s screening of “Molly’s Game.”

Elba has been married twice before. He has a 16-year-old daughter, Isan, with first wife Hanne “Kim” Norgaard, to whom he was married from 1999 to 2003. In 2006 he married American attorney Sonya Nicole Hamlin, but that union lasted only months. Elba has a second child, son Winston, who turns 4 in April, with former girlfriend Naiyana Garth.
