The unlikely pairing of Amber Heard and Christopher Walken pays comic dividends in “One More Time,” an agreeably predictable famous father/bitter daughter dramedy.

Walken plays Paul Lombard, an aged crooner, “The King of Romance,” contemplating a comeback as only Christopher Walken can. He’ll open for a more hip band and find a new audience.

“The FLAME-ing Lips,” he says, in Walkenspeak.

Heard is his struggling jingle-singing daughter, over 30 “wasting her talent” and determined not to let the old man or his agent (Oliver Platt) help her get a leg up.

Jude Lippman (Heard) was born “Star Shadow,” so-named by her six-times married dad, whose “makeout music” LPs are a go-to move for any unknowing guy about to bed her.

“It was my luck to be named during his ‘hippy’ period,” she grouses. And, knowing that makes no mathematical sense, “Who has a ‘hippy’ period in the ’80s?”

Paul lives…
