Hollywood A-listers John Travolta and Tom Cruise have attended the opening of the Church of Scientology's new "Super Power" building.

The actors were pictured applauding warmly alongside thousands of others as leader David Miscavige gave a short speech at the headquarters in Clearwater, Florida.

The enormous Flag Building has seven storeys and will reportedly be the only place scientologists can take part in the church's "Super Power" programme.

An estimated 6,000 scientologists attended the ceremony which was heavily-guarded by security personnel.

First advanced by church founder L. Ron Hubbard in the 1970s, this will allow scientologists to "create a new world".

The training regime involves using special machines to hone what Hubbard calls "perceptics".

He has been quoted as saying the Super Power "is the answer to a sick, a dying and dead society. With it, we literally revive the dead."

Church activists have been fundraising for the huge building since the 1990s.

According to the St Petersburg Times, the project has raised around $145million.
