This year marked 10 years since Thor hit theaters, which kicked off the Marvel careers of Chris Hemsworth (Thor) and Tom Hiddleston (Loki). The two actors are still extremely active in the MCU, having both just lent their voices to the latest episode of the new animated series, What If...? Hemsworth will be seen next in Thor: Love and Thunder, making him the first Avenger to get a fourth installment to their franchise within the franchise. Hiddleston just starred in Loki on Disney+, which has already been renewed for a second season. In a new "Untold" video from Disney, Hiddleston explained why Hemsworth was originally cast as Thor instead of him.
