Mark Hamill is a social media Jedi. When the new trailer and poster for Star Wars: The Last Jedi dropped yesterday, the fans came out in force to support and have fun with the goodies. Hamill was there, and ready to playfully poke fun at his fanbase.
Hamill's quote is a play on his quote from the trailer: "I have seen that kind of raw power before. It didn't scare me enough then. ... It does now."
Oh, and he also got into it with another Star actor (Trek, not Wars): William Shatner.
Star Wars: The Last Jedi has finished shooting and is due in theaters December 15.
