William Levy is in talks to star in Mockingjay, according to Latin Times.

According to the radio show “Fórmula Espectacular.” They reported that the producers of the movie are in talks with the actor’s representatives so he can join Jennifer Lawrence and Liam Hemsworth in “The Hunger Games: Mockingjay.”
Hmm... I would be very interested to know what character they want him to play? I can't really think of anybody. Perhaps Boggs or one of the District 13 solders (a stretch)? Maybe he is replacing Sam Clafin as Finnick...
