Is 'Katy Perry: Part Of Me' Like Every Other Concert Movie?

The trailer for "Katy Perry: Part of Me" dropped last night, and maybe it's just us, but something definitely looks familiar. There are sparks, slo-mo and a super-dramatic entrance, and you know what? It kind of looks like the trailer for a few of the 3D concert movies we've seen recently: Bieber, Miley, Jo Bros and "Glee."

We took a scientific approach—as we always do—and broke down each 3D concert movie trailer to see just how similar they are to the new one for "Part of Me." The results were intriguing...and in slow motion with sparks flying in the background.

"Justin Bieber: Never Say Never" (2011)

Of all the 3D concert trailers we checked out for our analysis, the Biebs had the most similar clip. Not only does "Never Say Never" feature pyrotechnics, backstage antics and a badass entrance, the trailer actually has a really similar structure. Both have lots of talk about their upbringing, Katy's being very Christian, while Justin's was—well—Canadian. The two singers both had people tell them there were things they couldn't do, which is shared through interviews and, in the case of Bieber, confusing title cards. ("They said it would NEVER happen. They said he would NEVER make it." Who said that?!?) There's also plenty of home video evidence and fan testimonials to back up those claims.

"Jonas Brothers: The 3D Concert Experience" (2009)

Coming in a close second, the Jonas Brothers put together a strikingly similar trailer, but it wasn't enough to edge out Bieber. They did, however, manage to share some qualities with "Part of Me" that "Never Say Never" was missing, fans crying, for instance. Everything else was there, lots of stage running, dramatic guitar moves. The Jo Bros also featured fan testimonials, but the similarity that we'll have to keep an eye on is the dramatic entrance, since it has been an essential element of each trailer so far.

"Glee: The 3D Concert Movie" (2011)

When it comes to similarities with the "Part of Me" trailer, "Glee" makes the mistake of having the actors play their characters backstage for the most part. There are still the behind-the-scenes hijinks, but none of the home video and "where they came from" voice over. There are sparks, though, lots and lots of sparks.

"Hannah Montana & Miley Cyrus: Best of Both Worlds Concert" (2008)

Though the main "trailer" for Miley Cyrus' 3D movie consists of little more than her talking directly into the camera, telling people to see it, a trailer for the Blu-ray release looks a lot more like the other trailers. That clip features the ever-present badass ascent-to-the-stage entrance, and it's almost entirely in slow motion.

"Katy Perry: Part of Me" hits theaters July 4.
