The Omen
On Friday, August 13, 1976, special effects artist John Richardson was in an accident in the Netherlands while working on A Bridge Too Far, also right after work on The Omen was done. Less than a year after designing the deaths for The Omen, Richardson's car was involved in a major accident which killed and decapitated his female companion, in a way similar to David Warner's death in The Omen. It is rumored that upon stumbling out of his car he saw a road sign that said he was near the town of Ommen, marked 66.6 km away.
