Twitter divided over Felicity Jones as Ruth Bader

The trailer of the movie 'On the Basis of Sex' has prompted varied opinions on whether Felicity Jones was the right choice for the lead role.

Netizens gave mixed reactions to the trailer, which showed Felicity as young Ginsburg, confronting age-old patriarch traditions.

A user tweeted, "Genuinely one of the most miscast leads I've ever seen. I was so excited about this movie when Natalie Portman was supposed to star in it!"

Another user wrote, "I like Felicity Jones but I find it really hard to believe there isn't an American actress better suited to this part."

However, there were many who appreciated Felicity's performance in the trailer.

One tweet read, "I'm calling it today, July 16, 2018, this will be Felicity Jones' second shot at the #Oscars, and I will be crossing my fingers for the win.#OnTheBasisOfSex

"So it's possible that #FelicityJones wins an Oscar for playing RBG the same year that #RBG wins an Oscar for Best Documentary...", read another tweet.

Directed by Mimi Leder of 'The Leftovers', the flick also stars Justin Theroux, Kathy Bates, Sam Waterston, Jack Reynor, and Cailee Spaeny in pivotal roles.

The film is slated to hit the theatres on December 25.
