Back in 2011 when Game of Thrones first arrived on HBO, Charlie Sheen was in the middle of his "tiger blood" meltdown, Adele's "Rolling in the Deep" topped the Billboard charts, Americans set their alarms for 3 a.m. to watch Kate Middleton's royal wedding, and many of the brand new fantasy series' stars were practically babies.

Sophie Turner, who plays Sansa Stark, was 15 when Season 1 aired. Maisie Williams, who plays Arya, was 14, and Isaac Hempstead Wright, who plays Bran, was 12. Over eight seasons, we've seen the actors and actresses grow up alongside their characters, and across the board, we've seen them glow up as well. Many of the cast members who were unknowns in Season 1 are now household names, with impressive projects lined up after Game of Thrones comes to an end in less than two months.
