Would you pay money to watch Will Ferrell play video games for two hours?

And no, it's not a new movie.

The U.S. actor will spend Oct. 26 playing video games live online, with the aim of raising a bumper contribution for two kids' charities.

“Will Ferrell's Super Mega Blast Max Charity Gaming Extravaganza” is set for a two-hour stint, broadcast from the offices of Amazon's latest acquisition, Twitch.TV in San Francisco.

A fundraising drive is being held via Indiegogo.com, with tiered donations able to net various and variously ridiculous Will Ferrell branded merchandise.

Those that donate $50 or more will be rewarded with a 4.5oz tube of dual-action sunscreen designed to prevent sunburn -- whether sustained outdoors or in front of a monitor or TV screen.

Apparel options start opening up at $75, with T-shirts and hoodies made available, while those more generous still can receive signed cowbells and Xbox controllers.

Should the total exceed $375,000, then one donator will be chosen via raffle to join Ferrell in San Francisco for his gaming mini-marathon.

"Word of my video gaming prowess actually broke the Internet, and now some of the best gamers in the world want a piece of me," he said in a jokey pitch video.

"I know the popular perception of gamers is that we are all extremely motivated, highly philanthropic and impossibly good looking. Let's not alter people's perceptions of us."

Partnering with Ferrell for the event are Twitch, Amazon and Xbox One. Its beneficiaries will be Cancer for College, which provides college scholarships to cancer survivors, and DonateGames, whose work includes the provision of video games to children in hospital.

The idea might sound odd, but as Ferrell explains, "games are also used as a form of therapy and help patients significantly during their treatment."

"I want more people need to know how video games can help and how benevolent the gaming community is."
