CREDITS THE OMEN , 1976 dir: Richard Donner Gregory Peck Lee Remick David Warner Billie Whitelaw Patrick Troughton Leo McKern

“Here is wisdom. Let him that hath understanding count the number of the beast; for it is the number of a man; and his number is 666. ”

The seminal horror film that spawned a whole genre of Antichrist movies.

There are brief trips to Rome (at the beginning) and Israel (to visit Bugenhagen), but most of the film is shot in the UK.

The exterior of the hospital, where the baby is switched, is Rome, sure enough, but the interior is the office of Shepperton Studio, Studios Road, Shepperton in Middlesex (which you might recognise as the interior of the O'Connell house in Stephen Sommers' The Mummy Returns).

Before things start to get nasty, young spawn-of-Satan Damien and his family enjoy a day out on Parliament Hill, part of Hampstead Heath near Highgate, north London.

'The Omen: the embassy: US Embassy, Grosvenor Square, Belgravia

US Ambassador Robert Thorn (Gregory Peck) is ensconced, naturally, at the American Embassy in Grosvenor Square, where he is confronted by crazy priest Father Brennan (Patrick Troughton, TV’s second Doctor Who). That really is the office of the US Ambassador, filmed in less security-conscious times.

Father Brennan spouts (fake) passages from Revelations alongside the Thames in Bishop's Park, at Putney, southwest London.

His nearby church, where he gets spiked by the lightning conductor, is All Saints Church, Fulham, which is actually on the north side of Putney Bridge.

Meanwhile, Damien is beginning to betray his diabolical leanings by throwing a major wobbly arriving at Guildford Cathedral and upsetting the monkeys at Windsor Safari Park, which closed in 1992. The site, just outside Windsor, is now the Legoland theme park.

'The Omen: the entrance to the home of US Ambassador Thorn: Pyrford Court, Pyrford Common Road, Woking

The palatial home of the US Ambassador, supposedly on ‘Seven Hills Road’, is Pyrford Court, Pyrford (which, at the time, was the deserted Guinness estate), a couple of miles east of Woking in Surrey. A private home, it’s well hidden behind a thick screen of trees and not visible from the road. You can, though, see the elaborate gatehouse, The Bothy, out of which Ambassador Thorn makes his final desperate drive, on the south side of Pyrford Common Road near Upshot Lane.

After suffering a fall in her home, Katherine Thorn (Lee Remick) recuperates in Northwick Park Hospital, Watford Road in Harrow, Middlesex.

'The Omen: Ambassador Thorn tries to kill his son: St Peter's Church, Laleham Road, Staines

The church, in which Thorn is finally thwarted after being convinced of the diabolical origins of young Damien, is St Peter's, Laleham Road, Staines, Middlesex.

'The Omen: Damien at the Ambassador's funeral: American Military Cemetery, Brookwood Cemetery, Brookwood, Surrey

In the creepy final scene, Damien attends the funeral of the Ambassador at the American Military Cemetery section of Brookwood Cemetery, Cemetery Pales, Brookwood, Surrey – once the country’s largest cemetery.
