Semi Bold

They're still using the former rebrand's Axiforma at present.

According to Pentagram's portfolio (Pentagram updated the Rotten Tomatoes brand identity), they modified Maax for the wordmark. You can read more about the rebrand on Pentagram's website: https://www.pentagram.com/work/rotten-tomatoes/story

For the actual prop, they didn't use a font, as it was handwritten by Miraphora Mina (one of the main graphic designers on all the Harry Potter – and now Fantastic Beasts – films).

The font you see here is a recreation which made by a fan (you can read about that here: http://10digitdesign.blogspot.com/2014/08/the-perfect-hogwarts-acceptance-letter.html)

A custom typeface designed by Dalton Maag for AT&T (who now own what used to be Time Warner Inc.). As a custom, proprietary typeface, it is not publicly available.

Modified.

The 2018 France TV rebrand extensively uses Brown (as ellouder2OMG already indicated). You can read more about this rebrand from (the Paris-based creative studio responsible for the rebrand) Movement at the links below:

The exact font is AntiqueBlack by Dover Publications from "24 Gothic Display Fonts".

The Doctor Who production team have started using Axiforma as the brand's font.

Hi MidnightStorm. I see andrewscorke has already suggested my remake of the American Horror Story font. I'd just like to inform you that I've updated the font to make it a bit more accessible through the addition of a second style called "Promo".

It is rather, isn't it?

The Doctor Who team have started using Axiforma as part of the rebrand.
