Emma Watson reportedly goes topless in her upcoming movie, "Regression." In the thriller-drama, the 24-year-old former Hogwarts alum played a very challenging role that could be her most risqué portrayal to date. Watson was cast alongside actor Ethan Hawke, Dale Dickey, Lothaire Bluteau and Devon Bostick.

Topless Emma Watson will definitely shocked her legion of fans. Her upcoming film, "Regression," depicts the tale of a father [John Gray], played by David Dencik, arrested for sexually abusing her daughter [Angela], the character that was portrayed by Watson. It is set in a small Minnesota town in 1990.

While Ethan Hawke played the role of Detective Bruce Kenner, the investigator to Angela's case. As reported by The Express UK, the unspeakable crime was unveiled after John unexpectedly and without recollection admits guilt to psychologist Dr. Raines [the character played by David Thewlis] is brought to help him recall his memories where they unveiled a disturbing national mystery.   

"Regression," which was written and directed by Alejandro Amenábar, is not released in the UK until in August 2015. However, the film is being previewed in US cinemas where viewers are expressing concern over Emma Watson's alleged topless scene, News.com.au reported.

As reported by The Sun, one moviegoer described Emma Watson's topless scene as "useless and ineffective."

"You can see her breasts but they are partially obscured. I think she may have been wearing pasties to cover her nipples," the moviegoer said.

Recently, Watson has made some cautious career choices to not stereotype her from the iconic "Harry Potter" character that made her gain her global prominence, New York Daily News reported. And aside from going topless on "Regression," Emma Watson will also be featured in the upcoming political drama entitled, "Colonia Dignidad." She even posted a picture from a scene on her Facebook account on Dec. 23.

"Colonia Dignidad" is a film by Florian Gallenberger which features Daniel Brühl and Michael Nyqvist. The film is being shot in Argentina and depicts the events that transpired during Chile's military coup in 1973.

Earlier this year, Watson made headlines when she delivered a highly-praised speech about feminism for the HeForShe campaign as a UN Women Goodwill Ambassador at a United Nations meeting in September. And earlier this month, Watson was hailed as Britain's most stylish at the 2014 British Fashion Awards and as Foundation for Women's Feminist Celebrity of 2014.

Emma Watson's topless news was first reported by London's The Sun. Does this mean that Emma is ready for more mature roles in the future?
