This Morning presenter Holly Willoughby impressed viewers in a scarlet dress as she joined co-host Philip Schofield for a spooky edition of the show.
The pair took on the roles of Miss Scarlett and Colonel Mustard as they participated in a Cluedo-style murder mystery, the Manchester Evening News reports.
But some viewers were left 'annoyed' by their antics and decided to switch off the ITV programme's annual Halloween episode.

Holly wowed fans in a stunning red floor-length strapless evening gown, which used to belong to her mum.
The stylish 40-year-old finished off her Miss Scarlett Halloween look with a diamond necklace and a fur shawl over one shoulder.
Meanwhile, Philip donned a fake moustache as he took on the role of Colonel Mustard, wearing a tweed suit accompanied by a bright yellow waistcoat.
The special edition of the show opened with dramatic scenes as The Lady of the Mansion, played by Josie Gibson, was murdered on the set.
This Morning invited viewers to play along and try and solve the whodunnit, which played out during the episode with the introduction of new characters along the way.
But the mystery twist left some viewers switching over.
"Totally cringe-worthy TV," one viewer wrote on Twitter. "I've turned it off."
"Is it too early to start drinking after watching that intro?" another asked, while another described the drama as "like watching kids in a nativity".
While fans were impressed with the presenters' costumes, it seemed their voice acting skills were not quite up to standard.
"Love the new look guys but already getting annoyed with the voices," one fan commented.
"Had to turn This Morning off. The stupid voices they are putting on are annoying," another said.
But not everyone was put off by the slightly unusual show, with some praising ITV for coming up with something new for Halloween this year.
"Loving This Morning already," one viewer said. "Such a great laugh to have after the time we had. Who cares if it's cringeworthy. It's just some fun and we need some fun on tv."
Meanwhile, viewers were also in awe of Holly's classy look, which fans describing her as "gorgeous".
"Can we just say how great Holly looks," one commented, while another said: "Have to say Holly looks fab in that dress."
Earlier in the week, Holly took to Instagram to hint to her 7.4 million followers which character she was set to play in the Cluedo reenactment.
The star showed off her pristinely shaped nails which had been polished using a shade of scarlet red.
In the photo, she was seen holding a number of board game pieces, including a toy goblet and a miniature knife.
She captioned the post: "A little 'Cluedo' as to who I'll be on this Thursday's @thismorning Halloween special."
This Morning airs on ITV weekdays from 10am to 12pm.
