The old F has a right hand side lower lip twitch which the new F lacks. He should have done the twitch when he finished speaking. He just sat there smuggly.
Old F body twitches when he makes a point, new one remains stationary.
New one gained facial fat and ditched the eyeglasses. At one point he lisped a bit and I wondered if he was wearing dentures.
Speech pattern is different. Old F is irritating, nervous like while the new one speaks normally and does not hesitate.
Good observation. speech pattern is off. Robin Williams could have done it slightly better. Always wondered about his suicide... He had to know what was going on.
As if reading or presenting a pre-written script?
