It's much ado about something.

Joss Whedon has directed, adapted, cast and filmed an entire movie -- an adaptation of Shakespeare's Much Ado About Nothing -- in secret, TheWrap has learned.

Whedon, who created Buffy the Vampire Slayer and Angel and wrote and directed Marvel's upcoming The Avengers, wrote and directed the movie, an individual close to the project told TheWrap Sunday night.

On Sunday night, a web site appeared announcing that Whedon's Much Ado About Nothing, which it says is based on a play, has completed principle photography. Two people close to the project confirmed that Whedon had indeed filmed a secret movie, and only announced it on Sunday night.

The independent film doesn't yet have distribution.

Actors include Sean Maher, who starred on Whedon's Firefly and in his 2005 movie Serenity; Fran Kranz, who stars in The Cabin in the Woods, which Whedon wrote and is producing; Castle, Firefly and Buffy the Vampire Slayer star Nathan Fillion and Angel and Cabin star Amy Acker. Spencer Treat Clark and Jillian Morgese, newcomers to Whedon's projects, also star.

Some of the actors took to Twitter to express excitement about the film Sunday night.

I promise you it's the real deal and we're VERY excited about it! Maher wrote.

He also tweeted, Surprise! We just wrapped today...

Shakespeare's Much Ado About Nothing is the kind of project Whedon likes. Its use of malapropisms appeals to Whedon's style, as do its characters who have unconventional views about love.

The play is a comedy about two sets of lovers. The fast-talking Benedick and Beatrice banter cynically while the sweet young Claudio and Hero are so in love they can barely speak.

Benedick and Beatrice get tricked into proclaiming their love for each other while Claudio is fooled into rejecting Hero at the altar. But the scheme is foiled and the two couples wed.
