The film is just out today, but Julie Delpy has already had to spend enough time convincing people that 2 Days in Paris — which she wrote, directed and stars in — is significantly different than Before Sunrise and Before Sunset, the two chatty, European-set relationship pictures she’s made with Ethan Hawke and director Richard Linklater.

After all, 2 Days in Paris follows a New York couple, French photographer Marion (Delpy), and American interior designer Jack (Adam Goldberg, above right), as they attempt to re-infuse their relationship with romance on the end leg of a European vacation. But the combination of Marion’s offbeat parents and a number of flirtatious ex-boyfriends, along with the natural language barrier, make for choppy waters.

Now Delpy’s working overtime to maintain that the film isn’t autobiographical, even though she and Goldberg used to date. “We were together for a short time, [but] truly, to me, it didn’t have much influence on the film — maybe more for him than me,” Delpy says. “For me, I’m very detached. When it’s over, it’s totally another world,” she says, adding a swooshing sound for emphasis.

Still, their relationship might have been grist for the creative mill. “I’ve always liked Adam for the idea of putting him in a movie more than being with him,” Delpy adds with a laugh. Then there’s a small pout of reflection. “I shouldn’t say that. He’s not going to be happy about that.”

Jesus. And one wonders why some folks are leery of dating actors and actresses…
