Earlier today, Tom Felton worked with director Richard Curtis (Four Weddings and a Funeral, Love Actually, Bridget Jones, etc.) to film a video to help promote awareness of a proposed “Robin Hood tax.”

According to the London Standard, the “Robin Hood tax” is an idea proposed by a group of more than 300 economists and businessmen, where there would be a small tax on financial transactions that occur only between large institutions. There are estimates it could raise more than £250 to £450 billion a year worldwide. This money could then be used to help fight global climate change

Bill Nighy, who also supports the proposal and has filmed a campaign video supporting it as well, told the Standard: “The thing about the Robin Hood tax is we ourselves searched for the flaws and there aren’t any. It’s one of those simply brilliant ideas that works for everybody and it’s slightly surprising that there should be any resistance from anyone.”

Watch the first campaign video with Bill Nighy below:

Other celebrities filmed alongside Tom today, as well, such as Ben Kingsley and Noel Clarke. Tom tweeted about it today:
