The world is still mourning the death of Carrie Fisher, aka Princess Leia. There were three other Star Wars actors who passed away this year.

Next year will mark the 40th anniversary of Star Wars: Episode IV - A New Hope. While we never like to think about it, the actors who starred in the original trilogy are no longer spring chickens.

We lost four Star Wars actors this year, including Carrie Fisher, who was the youngest to pass away out of the four at the age of 60.

Forever known as Princess Leia, Carrie Fisher passed away earlier this week after suffering a heart attack.

The man who brought R2-D2 to life, Kenny Baker, passed away in August, just 11 days shy of his 82nd birthday.

Drewe Henley played what came to be known as Red Leader in A New Hope. He had memorable lines like, "Cut the chatter, Red 2. Accelerate to attack speed." He's also the one that shoots the seemingly fatal shot to the Death Star, although we learn that the shot missed. This left it all up to Luke. Henley passed away in March.

Admiral Ackbar himself, who appeared in Return of the Jedi, leapt into the hearts of Star Wars fan with his most famous line, "It's a trap!" Bauersfeld also voiced Bib Fortuna, the weird guy with snake looking things coming out of his head in Jabba's lair. He passed away in April.
