The first teaser trailer for Saltburn, Oscar winner Emerald Fennell's hotly anticipated university romp, is here. The footage promises a lavish thriller of desire, privilege, and excess.

Banshees of Inisherin star Barry Keoghan plays the lead and was recently spotted filming scenes in Radcliffe Square in Oxford.

Set in the noughties, the twisted comedy-drama follows Oxford University student Oliver Quick (Keoghan), who finds himself intrigued by the world of his aristocratic peer, Felix Catton (Elordi).

Felix then invites Oliver to Saltburn, his family’s luxury estate, where they spend “a summer never to be forgotten” together.

In addition to Keoghan and Elordi, the “Saltburn” cast includes Rosamund Pike, Richard E. Grant, Alison Oliver, Ewan Mitchell, Archie Madekwe, Lolly Adefioe, Reece Shearsmith, Paul Rhys and Carey Mulligan, who starred in Fennell’s feature directorial debut “Promising Young Woman.”

“Saltburn” is set to open the 67th BFI London Film Festival on Oct. 4 at the Southbank Centre’s Royal Festival Hall in London.

“I’m honoured that our film is able to open this year’s BFI London Film Festival,” said Fennell, who can currently be seen as Midge in Greta Gerwig’s Barbie film.

“It is a festival that inspired me so much growing up, one that I followed excitedly from my bedroom on the other side of London. It feels extra-special that ‘Saltburn,’ this very British tale of excess, is able to make its international debut at the wonderful BFI.”

“Promising Young Woman” landed Fennell a Best Original Screenplay Oscar, as well as nods for Best Director and Best Picture. Mulligan also earned her second Oscar nomination for her performance as Cassandra in the provocative thriller.

Saltburn will have an opening night gala premiere at the Royal Festival Hall on October 4.

There will also be screenings of the film around the UK.
