why is Johansson so popular. There are plenty of prettier and better actresses out there. IMO
There is always a select group of actors and actresses that Hollywood,as a group, kind of anoint as the "next big things". They have always done this. They have actual ceremonies introducing the "stars of tomorrow".
Sometimes it works out. Sometimes it doesn't (they gave the "Action Star of Tomorrow" award to Howie Long in 1998 - on the pre release strength of *cough* FIRESTORM (oops)).
The next big actor is chosen before the public knows this particular actor has been anointed. So all of a sudden you have a rash of films from people you barely know (Joel Edgerton, Jai Courney, Sam Worthington, Margot Robbie) because they have been hit with that "buzz". And within the industry it becomes a thing. Producers will want this "new guy" because everyone else does (and they don't want to be left out), and the whole thing snowballs like crazy until you and I are left scratching our heads going "why do they keep putting F**king Jai Courtney in movies?!!!" after he has gotten the lead in ten movies based on the strength of....NOTHING. Just buzz.
If you look back at articles from the past, you can see all the actors who were dubbed the "next big thing" and never were: Johnny Whitworth, Hayden Christensen, Brandon Routh, Taylor Kitsch, Lily Collins, Monica Potter, Gabrielle Anwar....they were all hit with that tag - and pushed. But never panned out.
I think Scarlett Johannson is a decent enough actress. I have never seen her give an amazing performance in a film - but she is definitley competent enough. She chose her films well enough to have her name become a brand. She at least is an actress. Most "actresses" these days are just girls with no acting training or experience who skate on looks.
(And I still believe that if Johannson wasn't famous- and you saw her in real life, dressed normal- you wouldn't look twice....)
