Two megastars make a movie together and accidentally get married for real during a scene filmed on Valentine's Day.

How is that not already its own rom-com, starring the two people in question -- Keanu Reeves?

Winona and Keanu were love interests in "Destination Wedding," which we plan to see the minute it opens August 31.

During promotion for "Destination Wedding," the two stars -- no strangers to the word "kooky" -- looked back on their "Dracula" time, with Winona musing that they might actually BE married already.

Here's their convo with Entertainment Weekly:

Winona Ryder: “We actually got married in 'Dracula.' No, I swear to god I think we’re married in real life. In that scene, Francis [Ford Coppola] used a real Romanian priest. We shot the master and he did the whole thing. So I think we’re married."

Keanu Reeves: "It’s lovely to see you again."

Winona reminded him that they went through the whole ceremony and said "I do."

Keanu: "We said yes?"

Winona: "Don’t you that? It was on Valentine’s Day.”

Keanu: "Oh my gosh, we’re married."

Technically they are probably aren't married, even by whatever standards they had at the time in Romania. It's just a fun anecdote. But fans are 100 percent behind this '90s union ... except for the ones who are already fake married to Keanu or Winona themselves:

Winona and Keanu -- Weanu? Kinona? They deserve a sickeningly cute nickname, even if they aren't dating/married in real life -- also worked together in 2006's "The Private Lives of Pippa Lee."

"Destination Wedding" follows two grumpy, finicky strangers invited to a mutual friends' wedding. RSVP for tickets.
