Red The Angry Birds Movie begins on Bird Island, where most of the birds are peaceful and happy. But Red (voiced by Jason Sudeikis) has an anger problem and doesn't get along with the other birds.

Sentenced to anger management class, grumpy Red becomes a hero who trains his fellow birds to unleash their inner fury when pigs invade their island.

Audiences polled by CinemaScore gave the film an average grade of "B+" on an A+ to F scale. Lindsey Bahr of the Associated Press gave the film a positive review by writing, "Ultimately, The Angry Birds Movie does a decent job exploring the merits of anger.

Stella is Red's 2nd and main love interest of the Angry Birds Series. The two rarely argue in the comics and the main books of their relationship are "Princess and the Clown", "Red Hood" and "Angry Birds Transformers comic series". It is also shown in Angry Birds Pop Valentines event.
