Samuel L Jackson has turned teacher in an effort to try to improve voter turnout in the November US elections.

If 2,500 people take action via his HeadCount website to register for the forthcoming US elections, Jackson has promised to teach them to swear in 15 languages. Visitors to the site can click a button that allows them to register online to vote, check their voting status and find out how and where to vote in the US. The voting action is a partnership with campaigning site Global Citizen.

Whether Jackson’s free masterclass in swearing will be accessible to only to the first 2,500 who participate is unclear.

Jackson’s reputation as the sweariest actor in Hollywood was called into question last year after a survey found that Jonah Hill had beaten his record for the most curse words uttered on the big screen, thanks mainly to his role in The Wolf of Wall Street.

In April, Jackson urged people to “stay the fuck at home” as the pandemic worsened; previously, he narrated the audiobook version of the children’s book Go the F*ck to Sleep. Last month, it was announced that Jackson will reunite with his Hitman’s Bodyguard co-star Ryan Reynolds for an animated series called Futha Mucka.

Last December, Amazon unveiled an Alexa Echo add-on that allows users to request that the voice assistant direct a query to Jackson; an approved simulation of his voice delivers the reply.
