This Morning fans were left astounded as the show got off to a rather unusual start today.
All appeared to be normal during the opening titles until a tornado lifted Holly Willoughby's taxi off the ground and sent it plummeting into the studio.
Holly stepped out of the taxi in ruby red slippers dressed as Dorothy to a transformed studio.
It all quickly became clear that This Morning had undergone a remarkable Wizard of Oz style transformation.
The beloved presenter said: "Oh my goodness. I've got a feeling we're not on This Morning anymore."
Holly soon stumbled upon her fellow presenter Phillip Schofield dressed as a scarecrow hanging on a cross.
She said she would help Phil find his brain, before he burst into a rendition of "If I Only Had A Brain'.
Watch the video above to see Holly and Phil's incredible transformations.
Viewers quickly took to social media to express their initial confusion and eventual excitement.
One Twitter user asked: "WHAT. IS. HAPPENING. ON #ThisMorning?!!!!"
"Thought I was hallucinating for one moment" another added.
A third said: "OH MY GOSH! The show looks so amazing as #TheWizardOfOz for #Halloween
Phillip had to wake up at 4.30am to make sure he was in the dressing room ahead of his transformation.
This Morning airs weekdays at 10.30am on ITV.
