On the Headland Hotel’s website (which features an entire section on The Witches), there’s a detailed report about Atkinson falling asleep in his room after forgetting to turn off the faucet in his bath.
The hotel’s website also features a little blurb about Jack Nicholson (who was dating Anjelica Huston at the time) calling for Huston and sending flowers, which became a source of excitement.
Rowan Atkinson, better known to most as Mr. Bean, appears in a pretty major role as the hotel manager in The Witches, but an incident at the Headland Hotel where the move was being filmed nearly ruined everything.
His bedroom happened to be above the production office and the water from his overflowing bath made its way through the floors and into the office, ruining all sorts of equipment.
