Jennifer Aniston Keeps It Simple at the "Horrible Bosses" Premiere (Fashion Wire Daily)

Los Angeles – Summer is in full swing in Hollywood, which made it simple for Jennifer Aniston to get dressed for the premiere of her raunchy new comedy "Horrible Bosses." The actress slipped into a glittery little black minidress and a pair of strappy black sandals, and she was good to go on Thursday, June 30, off to Grauman's Chinese Theatre along with her new boyfriend, actor Justin Theroux.

But Theroux avoided the red carpet frenzy and slipped in a side door, as Aniston joined "Horrible Bosses" director Seth Gordon and her gang of co-stars on the extra-long walk into the theater. There are so many popular actors in "Horrible Bosses" who came out for the party, including Jamie Foxx, Jason Bateman, Julie Bowen, Jason Sudeikis, Isaiah Mustafa, Lindsay Sloane, Ioan Gruffudd and Charlie Day, that it took longer than usual for the photos and interviews to finish up.

Aniston, who plays a foul-mouthed, sexually inappropriate dentist, and a very bad boss in the film, loved getting the chance to change things up, starting with her look and finishing with a very bad attitude.

"I knew I wanted her to look different. I wanted her to have dark hair," Aniston told reporters at an earlier press conference. But that idea didn't go over very well with the executives at New Line Cinema, who wanted her to keep that signature hair of hers, despite the fact that she plays a despicable person, a character that is nothing like the Aniston audiences usually see on screen.

"We had this wonderful period of time that we called 'Hairgate,' because the studio was refusing, they did not want me to wear the dark wig, like, 'Nobody will know who you are!' I'm like, 'What do you mean? They'll know who I am because of my name in the credits, I hope.' I said, 'There's just no way I can be saying these words and playing this woman and not look somewhat different.'" Obviously, Aniston's star power won out, and she's a dark brunette in the movie.

Other comedy fans on hand for the premiere were Aniston's best girlfriend Chelsea Handler, Jennifer Love Hewitt, Jenna Elfman and Alyssa Milano.

Sarah Palin documentary to premiere Tuesday in Iowa (Reuters)

LOS ANGELES (Hollywood Reporter) – The Sarah Palin film "The Undefeated" has booked a 111-year historical landmark in Iowa for its world premiere next week.

The premiere is scheduled at 5 p.m. central time Tuesday at the Pella Opera House, a venue that hosted live stage plays before hitting its stride with silent movies in the early part of the last century.

"Undefeated" is the well-hyped documentary about the former vice presidential candidate from Victory Film Group and ARC Entertainment that was written and directed by Stephen Bannon. It was produced by Bannon and Victory's Dan Fleuette and Glenn Evans.

The moviemakers have extended an invitation to Palin, though she has not committed to attending. It was unclear Friday whether others featured in the film - Andrew Breitbart, Tammy Bruce, Mark Levin and other pundits - would attend, either.

Organizers on Friday also wouldn't commit as to whether or not red carpet arrivals were planned, but said the premiere is for 320 invited guests only.

"Undefeated" begins limited release on July 15 at 10 AMC theaters in Dallas, Denver, Oklahoma City, Orlando, Atlanta, Orange County, Phoenix, Houston, Indianapolis and Independence, Missouri.

At the film's website, they're asking visitors to vote on which other AMC theaters ought to show the film, though plans for wider release were vague Friday.
