Those who watch Whedon know he tends to use the same actors over and over again. Collectively they are known as the “Whedonverse”. (Apparently.)
Anyway, Buzzfeed has a great story about the stars of the Whedonverse, and how Rick Castle, Agent Coulson, and Wesley Wyndham-Pryce, the Watcher, came to star in a black-and-white modernized edition of Much Ado About Nothing.
Made in 12 days by Joss Whedon at his own home (in between wrapping The Avengers and post-production on same), it is a much lauded version of Shakespeare’s complex tale of jealousy, infidelity, and love.
