What is the theme from 'Donnie Darko' doing in a new film about the founder of WikiLeaks? That familiar song appears in the trailer to the upcoming TV movie 'Underground: The Julian Assange Story.' What's the name of the song?

It's 'Mad World' by Gary Jules and Michael Andrews. Their haunting piano cover of the 1982 Tears for Fears track plays during the 78-second trailer, which consists entirely of computer text being typed on a white screen, aside from one brief image of Assange himself.

The text explains that Assange got his start as a teen in Australia hacking government systems worldwide before attracting the attention of international law enforcement. Assange went on to create WikiLeaks, where he got into hot water for publishing classified U.S. military documents.

'Underground: The Julian Assange Story' is expected to air on Australian television in October, with possible showings in other countries after that. It premiered this week at the Toronto Film Festival, earning positive reviews.

The Jules and Andrews version of 'Mad World' became a hit single after it was featured in the final scene of 'Donnie Darko'. The song reached No. 1 on the British singles chart in 2003.
