Finnick didn't choose Peeta over Mags. He could only carry one and Mags knew Finnick was going to choose to save her over Peeta so she decided to walk into the fog so finnick wouldn't save her
In catching fire finnick is 24. Hope that answers your question
The actor for Finnick is undecided.
I really really like finnick. i have a crush on him ;)
Finnick is from District 4, the fishing district.
The book never actually mentions Finnick and Annie's baby's name. It just refers to it as 'Finnick and Annie's newborn son'. However, I feel that the baby should be called Finnick (Jr) Neal Odair and be nicknamed Fin.
Finnick Odair is the male victor from District 4, which specialises in fishing.
Nope. It was said that Mags was Finnick's mentor. :)
I don't believe that Suzanne Collins ever names Finnick and Annie's son.
Finnick actually doesn't die in Catching Fire
Yes. This happens in the third book in the Hunger Games series, Mockingjay. Finnick and Annie get married in District 13, and Peeta Mellark bakes their wedding cake. Finnick wears one of Peeta's suits. Annie wears Katniss's outfit from visiting District 5. Later on, Finnick dies, and Annie has a baby. The baby is Finnick's.
No he isn't. But he did do a calendar photoshoot in which one of the photos, he dressed up as Finnick.
