Actually I did not recognize the female actress Felicity Jones but she did a very good job in the Stephen Hawking film “The Theory of everything” But in that she played a struggling wife coming to terms with her husbands regression in to becoming disabled. It was as much about her as it was about Stephen Hawking
She did do ever so well in this so perhaps she might just be a bit misunderstood the way the trailer is made but then again look at Natalie Portman who was sheer brilliance in Black Swan but awful in the Star Wars Prequels.
It really does not matter if it’s a woman or a man in the Lead role but it is important to find the right person who can believe in the fantasy.
