I think Porthos should never shave. He suits the face fuzz so much more than in RL where he has a very baby face. He was designed to look scary.
Can you imagine when they start filming, just how much they are all going to up the sexy factor. They must be aware of all the attention and slightly obsessive fans out there building internet shrines to them.
I am expecting to see a massive increase in their signature phwoar moves.
So obvs Athos will lean on everything, permanently. And his voice will always be of the remove your knickers immediately it will be our duty and our pleasure, tone.
Aramis will smack everything with books, and do his doff hat thing, and also his no looking thing.
If Richelieu was still in it he would be even colder, and he would finger everything.
Porthos would do his menacing smile and just throw people. Although after last night, he should definitely get more love scenes. Phwoarrrrr! get your guns out
..and leather will increase a hundred fold. And they will wear so much sexy strappy bits and weapons they can barely stand without tilting to the side/front/back.
