Tom Cruise is at it again in yet another wacky Scientology video, but this time the Mission Impossible star says more with excited dance moves and actions rather than words.

The footage, seen on video sharing site YouTube, dates back to 2004, and shows the actor at a birthday party which was thrown for him by his fellow Scientologists.

The latest video - where Cruise says little but sings and dances about - follows the release of footage in January where Cruise talks about his devotion to Scientology.

The 5 1/2 minute birthday footage shows the actor walking into the party to the Top Gun tune while he's surrounded by other Scientologists who are clapping and dressed in white.

The party, which reportedly cost a six figure sum, shows Tom clapping excitedly before getting on stage with a singer while images of his movies are shown on a background screen.

At one stage, Cruise sings along and does the splits while those around him punch the air and clap wildly.

"Whoa... This is the best birthday party ever... I don't know where I am, it's crazy," he said.

In the earlier video, Cruise talks of his religion and how it is able to "rehabilitate criminals" as well as "bring peace and unite cultures".

The video was for Scientologists' eyes only and not meant for public view.

He also says: "Being a scientologist, you look at someone, and you know absolutely that you can help them."

He issued a rallying cry to other Scientologists to change the world, saying: "Now is the time", and confessed he was "dedicated" to taking Scientology to the masses.

He goes on: "I have to tell you something, it is rough and tumble, and it's wild and woolly, and it's a blast, it's a blast, it really is fun because, dammit, there is nothing better than going out there and fighting the fight and suddenly you see things are better.

"I do what I can, and I do it the way I do everything. There's nothing part of the way for me."
