Vince Vaughn plays Santa's brother

There's benefits to being the brother or sister of a prime minister, president, Nobel prize winner, sports star or Oscar winner.
There's probably plenty of negatives about living in a successful sibling's shadow.
Imagine being the brother of Santa Claus.
The plus would be St Nick would not be stingy with presents for the family each Christmas and you could probably score a ride on Rudolph or Blitzen, but it's a large, rotund shadow to live in if you're his brother or sister.
How could you compete with one of the world's most beloved men?
It's a concept Hollywood studio Warner Bros explores in its new family Christmas comedy, Fred Claus, with lanky comedian Vince Vaughn playing Santa's under-achieving brother.
Paul Giamatti, the star of Sideways and Cinderella Man, fills the role of Santa.
With Vaughn standing just under 2m tall, and Giamatti, a balding red head at the other end of the height scale at 1.74m, it's the oddest brother casting since Arnold Schwarzenegger and Danny DeVito teamed up in the 1988 comedy, Twins.
Vaughn, 37, who last year was a target for the paparazzi when he became Jennifer Aniston's first love interest since her break-up with Brad Pitt, says there is no sibling rivalry with his two sisters, who are five and six years older.
Vaughn's Hollywood career, including recent high-grossing comedies Wedding Crashers, The Break-Up and his breakthrough role in 1996's Swingers, reached a milestone with Fred Claus, picking up a reported $US20 million ($A21.63 million) pay packet.
It places him in an elite earning club that includes Tom Cruise, Russell Crowe, Jim Carrey, Adam Sandler and Julia Roberts.
Back when he was a kid, things in the Vaughn home in Minneapolis, Minnesota, were not so jovial.
Sibling rivalry with his sisters, Victoria and Valeri, was out of control.
"I was the youngest," Vaughn told reporters during an interview on the Warner Bros lot.
"I had two older sisters and we would play board games like Monopoly and they didn't want me to play.
"They'd yell out to mum 'He's knocking over all the pieces' and because they were older they would be allowed to go out and do more things than me.
"And they'd say, 'Why doesn't he do more around the house? When we were his age we had to cut the grass'.
"Then as you get older and get out of the house it changed.
"We're really tight now and they're my best friends.
"We laugh at all that stuff now."
His sisters also played a role in one of his most disappointing Christmas memories.
Vaughn was six-years-old and two older kids who lived next door to his family delivered some unwanted news to him.
"They said: 'You know there's not a Santa Claus, right?'," Vaughn recalled.
"Of course you don't want to be caught off guard so you say 'Yeah, yeah, yeah I know.'
"Then I went and saw my sisters who were five and six years older than me, so they were 11 and 12, and I felt so betrayed.
"My sisters were like, 'OK, be quiet, but you can't tell mum and dad you know or we're not going to get gifts anymore'.
"I felt I had to keep it going or otherwise we wouldn't get any gifts.
"So, years on I was 16 years old and shaving and still saying 'So when's Santa coming? When's Santa coming?'."
Vaughn and Aniston broke up earlier this year.
He had been friends with Pitt, co-starring with the actor on the 2005 action-comedy, Mr and Mrs Smith. It was on Mr and Mrs Smith where sparks began to fly between Pitt and the film's female lead, Angelina Jolie.
Vaughn and Aniston teamed up a year later on the ironically titled romantic comedy, The Break-Up, where their friendship turned into romance.
The public exposure was a relatively new experience for Vaughn, whose previous romances never put him on the cover of The National Enquirer.
He has no regrets.
"If you like someone you like someone," Vaughn said.
"I think when you're younger we all say 'I'll never date anyone like this' but then you end up dating someone like that because that's what love is.
"You can't pick it from a logical place.
"You connect with people.
"For me the people I've dated for any period of time, there's always a friendship there.
"I think that becomes the ultimate thing."
The actor said the media landscape in Hollywood had dramatically changed in the past 20 years.
"When I first came out to LA I was 18 and there was only one show focused on celebrities and that was Entertainment Tonight," he said.
"There was no E! channel and my friends, like the guys from Swingers, were all vulnerable actors and none of us ever even thought about being famous.
"We wondered if we could be working actors.
"I was happy to get a TV commercial or a couple of lines on TV show."
