Hollywood actress Reese Witherspoon is not keen to star in science fiction movies as the genre does not offer substantial roles to female leads.

“The movies that are being made feel different. There are a lot of really, really big movies about robots and things – and there”s not a part for a 34-year-old woman in a robot movie,” said Witherspoon.

The ”Legally Blonde” star feels the futuristic films are limited to ”superhero” roles and therefore, does not interest her, Contactmusic reported.

“I”ve never done the superhero movie. That doesn”t interest me too much.”

Drastic change in the film industry has made the actress selective about her work, and when she is not doing a film her daughter Ava and son Deacon keep her busy.

“I also have kids, so when I”m not working, it”s not like I”m sitting around doing nothing. I”m taking care of two kids who are rapidly growing up in some bizarre time warp. I mean, somehow I now have an 11 year old!” said Witherspoon.
