Matt Dillon sprung into action at LAX yesterday -- when a woman waiting in line in front of him suddenly collapsed and slammed her head on the terminal floor.

Dillon helped the woman over to a nearby seat ... and stayed with her while airport staff got her water and called paramedics.
An L.A. Fire Department medical response team rushed to the scene and wheeled the woman into a waiting ambulance.
So far, no word on the woman's condition.
There's something about
Matt Dillon.

Here's the 23-year-old "Flamingo Kid" back in 1987 (
left) - and 22 years later, the 45-year-old version at some event in NYC last week (
right).
He's to die for.

Maybe Matt Dillon should have been considered for the "Mission Impossible" spy role instead of Tom Cruise -- because he's gone undercover!
The normally serious and always depressed-looking actor was spotted at a Coffee Bean by a TMZ staffer over the weekend, and instead of giving the barista his real name, the super slick Dillon told them his name was Joe.
Yes, he's that lame.
Matt Dillon decided not to shoot his snide remarks at one of the adult photogs at Il Fornaio -- instead spewing an insult to the only underaged snapper on the sidewalk, Austin.
Wahhh. I'm Matt Dillon. Wahhhh.
TMZ caught Janice Dickinson attempting to "save" the world's critters from Paris and Britney -- well, at least the puppies in the Malibu Country Mart! Also in L.A, hunky Matt Dillon drivin' his Benz as a photog makes a waggish remark, the usually smirky Damon Wayons outside of Mr. Chow - not smiling, and studly Hayden Christensen chatting up the paps at LAX.
On the opposite coast, Sandra Bullock and Anne Hathaway both receiving warm paparazzi greetings as they arrive at NYC airports.
Matt Dillon isn't familar with how TMZ treats people
who like to hit.
Without saying a solitary word, the
other Dillon brother walked right up to a TMZ photog in New York this weekend and
smacked the s**t out of his camera. Not cool, dude! After the sneak attack, the not-so-tough guy walked off in a huff -- only to stop a few seconds later to stare down our shooter.
What's he so pissed about? It was the public that had to endure "You, Me and Dupree"!
In a statement to TMZ, Dillon's rep claims "You don't show the part of the footage where the photographer kept hassling him. He wouldn't have pushed the camera away if he hadn't."
For the record, that footage doesn't exist as our photog shot every frame of footage from the other side of the street -- until Dillon approached
him.
After nearly 30 years in the business, Matt Dillon finds himself suddenly at the top of his game.

Dillon tells
Parade magazine that his Oscar nomination for "Crash" earlier this year "reinvigorated" him both professionally and personally.

In "You, Me and Dupree" Owen Wilson once again plays the uninvited guest, only instead of crashing weddings this time he's a really annoying guy crashing on a friend's couch.
Wilson plays Dupree and told reporters
at the Hollywood premiere of the film last night that there's definitely a little bit of his character in him.
"I think for my older brother I was a little bit of a Dupree when he was first married. Sometimes they would even try to lock me out to get some privacy. One time I had to go in to get some clothes and I ended up going through the crawl space and falling through the ceilings. That didn't help the marriage."

Kate Hudson, Matt Dillon and funny man Owen Wilson are grouping together for a summer laughfest in their new movie "You, Me and DuPree."
Matt Dillon plays Carl Peterson, Kate Hudson's husband in the flim, and describes his onscreen wife as "endearing, as well as easy on the eyes," and when being asked about having a possible crush on his co-star he admits "It's kind of hard not to."
Owen Wilson plays best friend to Carl and annoyance to Hudson's Molly, felt a little pressure from his stunning blonde co-star. Hudson clearly has gold popcorn statues in her dreams and told Wilson,"If we dont get the MTV award for Best Kiss, it's not worth it."
Kate's always been easy on the eyes but her life has gotten even hotter since picking up a sexy extracurricular activity: pole-dancing.
When asked about her new obsession she gushes that "It's so much fun, it's the best time."
"You, Me and Dupree" opens in theaters everywhere July, 14th.

The cast of 'Entourage' showed up Wednesday night at Buddha in New York to celebrate the launch of the HBO show's third season.
TMZ's cameras caught up with 'Entourage's'
Jeremy Piven, Kevin Dillon, Matt Dillon and Adrian Grenier, as well as one of Hollywood's hottest young couples -- Kevin Connolly and Nicky Hilton. 'Entourage' producer Mark Wahlberg was there to bask in the popularity of the show, as were James Woods, Piper Perabo, and hip hop mogul Russell Simmons.
