At Sundance, stars are usually raring to talk about their fledgling films.
That wasn't the case, though, with French beauty Julie Delpy.
The actress was in town to unveil 2 Days in New York, a family farce costarring Chris Rock that she wrote and directed, and on Wednesday she sat down for a panel discussion about it.
But about 15 minutes before the talk was scheduled to end, she abruptly left and didn't come back.
Pourquoi, er, why, you might ask?
E! News confirms that the star was suffering from a migraine, which likely spurred the early adieu.
According to Vulture, Delpy actually went to the hospital and her fellow panelists, who included Parker Posey, only found out about it afterward.
The star's rep wouldn't comment about hospitalization reports, although she did confirm to us that the star is now feeling fine.
When the talk began, Delpy already exhibited some funky healthy symptoms. Footage of the discussion shows the director-actress squinting and having trouble opening her eyes. This prompted someone in the audience to hand her a pair of shades, to which she quipped, "I feel like Keith Richards."
Delpy, who recently revealed to Deadline that she's thinking of retiring from acting, is the latest celeb to succumb to what appears to be a Sundance 2012 health curse. Tracy Morgan was rushed to a hospital last Sunday after collapsing at an awards gala there, and indie-film veteran Bingham Ray died the following day after suffering a stroke at Sundance.
Here's hoping Delpy doesn't need those shades anymore!
