Indiana Jones’ Golden Idol
This easter egg can be seen in all versions of the movie.
After Gru gets fired from the AVL and breaks the news to the Minions, Mel, the Minion leader shows Gru a slideshow of things they liked about him being evil versus the good tasks that he performs now. One of these evil tasks being Gru stealing a golden statue from a museum while dodging alarm lasers.
Fans of the Indiana Jones franchise may recognize this statue for it’s high resemblance to the Golden Idol from Indiana Jones and the Raiders of the Lost Ark due to it’s large, open mouth and golden color.
