Idina Menzel's "Let It Go" is widely recognized as one of the great factors in the success of the Disney animation, "Frozen," which was released in 2013. However, it seems that Menzel, the voice behind Elsa, will not be able to take part in the sequel of the movie which is set to premiere in 2018.

Reports suggest that Menzel might be forced out of the sequel in preparation for her wedding, although the actress has not confirmed nor denied her exit yet. With Disney being mum on the issue, a lot of names have been tagged as possible replacement of Menzel.

The strong candidate for the role is Demi Lovato who is also a former Disney Channel star. It can be remembered that Lovato's rendition of "Let It Go" was considered to be as good as that of Menzel. Accordingly, her voice range is the closest to Menzel, so it is not surprising if she will be given the role. Aside from her, other recommended singers include Taylor Swift, Ariana Grande and Rihanna.

Should Menzel get through her plan of exiting the movie, the original cast members will only include Kristen Bell (Anna), Josh Gad (Olaf), Jonathan Groff (Kristoff) and Santino Fontana (Hans).

Aside from the songs, the plot of "Frozen" was as good and as important factor in the movie. Hence, rumors suggest that love stories of Elsa and Olaf will possibly be highlighted. Accordingly, it will be revealed that Olaf is a human being trapped into the snowman's body and is expected to show his true form in "Frozen 2."

However, a revolutionary theme is being suggested to Disney Channel for the sequel of the movie. Accordingly, some fans suggest that Elsa should portray a sense of homosexual relationship as she eventually falls in love with a woman, but Disney has not said anything about this suggestion yet.

"Frozen 2" is expected to premiere in 2018.
