For it is :
- Preparing a huge breakfast and then they take a bit and they say I need to go
- People drinking coffee or other drinks but you see clearly that they don’t, why film that ?
- Turing the wheel of the car like crazy when they on a straight road.
- Wearing shoes inside the house even when they are about to go to sleep.
It is not that difficult as other directors do it well. I see that in Japanese shows. It is OK if actors pretend to eat or drink when it is believable. In many episodes of Seinfeld we see the actors drinking coffee but we can clearly see that they weren’t taking a sip.
