1. How are the backgrounds and floor effects done on shows like
Dancing on Ice and Who wants to be a Millionaire. If projected, why
don't the presenters get in the way?

On Millionaire, it's all real stuff. The floor is transparent with
lights below it. The rest is movable spotlights. The backgrounds are
all real.

I know. I was on it.

The amusing part is the pedestal in the middle. Not there during
Fastest Finger First. When that finishes, Tarrant takes the winning
candidate by the arm and starts to walk them to the centre. Then they
stop the recording and send them off for extra makeup. Then they wheel
the pedestal in, and someone crawls under the floor to plug it in.
When the contestant returns, they set up the same pose by using a
freeze frame of their previous position as a reference. The 'flash'
arrival of the pedestal is hidden behind a bit of balcony.




Many thanks.
