In order to re-create the madness that went down at a [artist id="13432"]Biggie[/artist] concert, the cast and crew of [movie id="360770"]"Notorious"[/movie] made sure they got every little detail right, including the clothes, the hair and, most importantly, the vibe.

"I want to make it feel like a concert," director George Tillman Jr. said during a visit to the set of the [article id="1598021"]Notorious B.I.G. biopic[/article], which hits theaters January 16. "Like you're right there in the middle of a show. ... On that day, it felt like I was performing with [Big], 'cause you go out backstage to shoot scenes, you see entourages, you see people with their own cliques hanging out. I felt like I was with a rap star."

For the film's performance footage, Tillman rounded up the usual suspects that one might have seen at a Biggie concert during the '90s, including producers, DJs, managers and a cast of actors that looked uncannily like the people they are portraying.

"Performances, that's what I do" said Jamal "Gravy" Woolard, who [article id="1582881"]plays Biggie in the film[/article]. "I'm gonna make you feel like you see him up there. Like he's not gone. That's what I got to do."

Naturi Naughton, who plays Lil' Kim, was convinced by the vibe of the faux concert: "I feel like I'm at a real show."

The whole scene [article id="1600918"]was approved[/article] by Biggie's real-life right-hand man, [artist id="1244169"]Diddy[/artist], who showed up to give the movie mob his stamp of approval. "All of these actors up here did a great job," he said, surprising the crowd from the stage at the Hammerstein Ballroom in New York.

"I felt like it was important to get it right, because a lot of people have not seen Big perform," Tillman said. "Everyone came and brought it. Every moment was there on camera: the fun stuff, the great stuff."
