Well, the McConaissance is official, as Matthew McConaughey walked away with his first Oscar on Sunday night for his performance in “Dallas Buyers Club.”

“It’s a scientific fact that gratitude reciprocates,” said Matthew McConaughey, who appeared on the verge of tears as he thanked God, his family and the Academy. Naturally, he wrapped up his speech with a shout-out to his famous “Dazed and Confused” line: “Alright, alright alright” and “Just keep livin’.”

His win wasn’t exactly a surprise: McConaughey, 44, who lost an extreme amount of weight to play AIDS patient Ron Woodruff in the film, has been unstoppable this award season. He picked up Best Actor trophies everywhere from the Golden Globes to the SAG Awards to the Independent Spirit Awards. He immediately became a Twitter sensation after the Globes, starting with the “alright, alright, alright” line and making everyone excited for a McConaughey sweep of awards.

Who would have thought? Over the course of two decades, McConaughey went from starring in stoner flicks to becoming a rom-com king to HBO show star to Academy Award winner. Here’s a look back at some of his most iconic career moments leading up to his first-time Oscar win:
