LOS ANGELES —”Fifty Shades of Grey” didn’t relinquish control of the box office.

Universal’s erotic drama starring Dakota Johnson and Jamie Dornan earned $23.2 million at No. 1 in its second weekend at the box office, according to studio estimates Sunday. The adaptation of E.L. James’ best-selling novel earned an additional $68.1 million overseas.

Despite the victory, director Sam Taylor-Johnson’s “Fifty Shades of Grey” plummeted a steep 73 percent from its record-breaking $85 million three-day debut over President’s Day weekend.

“Kingsman: The Secret Service” and “The SpongeBob Movie: Sponge Out of Water” kept their respective No. 2 and No. 3 spots at the box office.
