Taylor Kitsch, Garrett Hedlund and Armie Hammer have all been linked to the role of Finnick Odair in 'Catching Fire'.
Finnick is the victor of the 65th Hunger Games in the Suzanne Collins book trilogy on which the movies are based and his role is a vital one in the second novel.
According to E! News, film bosses are undecided about whether to go with one of these three actors or launch an unknown with the pivotal role. A decision is expected to be made this week.
However, Lionsgate refused to comment, with a representative saying: ''As with the first film, we won't be confirming, denying or commenting on any casting rumors for this title. We will announce news wide when there is official casting news to announce.''
Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth all starred in 'The Hunger Games', which was released earlier this year and are on board to reprise their roles of Katniss Everdeen, Peeta Mellark and Gale Hawthorne respectively.
