According to the
Hollywood Reporter, four more roles have been cast:
Sam Ly as District 7 Tribute Boy
Leigha Hancock as District 7 Tribute Girl
Samuel Tan as District 8 Tribute Boy and
Mackenzie Lintz as District 8 Tribute Girl.
Only for few more to go and it will be the full roster. Haymitch is going to be a really key one, I think.
