The Perks of Being a Wallflower and Resident Evil: Retribution are just two of the new contenders debuting at the box office this weekend — and both are facing demons of their own.

Starring Logan Lerman, Emma Watson and Ezra Miller, Perks revolves around a young boy who is forced to face high school alone after his one and only friend commits suicide the summer before. In an attempt to get his mind off his dark, traumatizing thoughts, he befriends a quirky senior brother-and-sister duo who introduces to a world of sex, drugs and indie music.

What’s Resident Evil: Retribution fending off this weekend?

Aside from actual contending movies like Finding Nemo 3D and P.T. Anderson‘s The Master, the movie boasts plenty of butt-kicking as everyone’s favorite zombie killer for the successful franchise’s fifth installment.

Milla Jovovich reprises her role as Alice, the super-human who time and time again must stop the evil Umbrella Corporation’s T-virus from infecting the innocent.

Resident Evil actress Michelle Rodriguez also returns in this installment after being killed off in the first movie.

Which movie will you watch this weekend. Sound off in the comments below.

Erza Miller was mighty impressed by Emma Watson’s American accent in The Perks of Being a Wallflower, a factoid he revealed to Celebuzz Monday night at the film’s Los Angeles premiere.

“You know, Logan and I had a conversation once,” the 19-year-old actor — who attended the event with a cardboard cutout of his absent co-star, Logan Lerman — revealed. “We were like, ‘Hey, you think Emma’s going to be able to do an American accent like we can, because we are from America?’”

So, what was the final verdict?

“We were like, ‘Probably, she’s pretty awesome.’ Then, after we saw the movie a couple days ago, we were like, ‘Yup, we were right.’”

But it wasn’t just the British-born Watson’s accent that impressed Miller. In the video above, the actor spoke about the close relationship he formed with Lerman and Watson while filming the movie, calling the experience one of the best summers of his life.

“We formed a really close bond,” he said.

“[It was the] kind of experience that the book is about, where you kind of realize in these beautiful moments that friends will get your through.”

And speaking of one-of-a-kind experiences, stay tuned to the very end of the video to find out what happened when Miller pulled the Lerman cutout in for a quick interview.

Suffice to say, he didn’t hold out as well as the real Loman would have on the red carpet.

The Perks of Being a Wallflower hits theaters on Sept. 21.

Emma Watson fans got a look at the actress’ first big post-Harry Potter role Wednesday when Lionsgate released a new clip from The Perks of Being a Wallflower.

The film, which co-stars Logan Lerman (Percy Jackson) and Ezra Miller (We Need to Talk About Kevin), follows a young man’s journey through high school as he experiences adolescent romance, drug experimentation and suicide.

What happens when a Harry Potter alum meets Percy Jackson?

In the clip, Watson’s character Sam joins her step-brother Patrick (Miller) in a toast to Charlie (Lerman), the “wallflower” of the film’s title. Patrick leads the tribute, observing of Charlie, “You see things and you understand. You’re a wallflower.”

Charlie responds, “I didn’t think anyone noticed me.”

Patrick reassures him as Sam invites him to join their social group: “Welcome to the island of Misfit Toys,” she says.

Watch the clip above for a look at Watson’s cropped hairdo and her post-Potter style. The Perks of Being a Wallflower opens in theaters September 21, 2012.
