Dermot Mulroney shares 'Young Guns' reunion photo with Emilio Estevez and original cast members

A number of iconic '80s heartthrobs reunited for a group selfie nearly 40 years after their Western film "Young Guns" was released.

Earlier this week, actor Dermot Mulroney made a joint Instagram post with Emilio Estèvez. Both starred in the 1988 movie. 

"38 years later #youngguns rides again - PALS," the caption of the post read.

NOAH WYLE, MATT DAMON, LEONARDO DICAPRIO STILL CAPTIVATING AUDIENCES WELL INTO THEIR 50S

Also in the selfie was Charlie Sheen, Estèvez's brother; Kiefer Sutherland; Casey Siemaszko; Lou Diamond Phillips; and Terry O'Quinn. The cast of the movie reunited at a fan event in Dallas, Texas, Saturday.

Fans flooded the comment section of the post, praising the men for never aging.

"Does Emilio Estevez ever age? He has the secret to the fountain of youth," one user wrote.

"Emilio looking younger than all of them!" another wrote.

Another Instagram user commented, "If that isn't the most epic reunion I don't know what is!!!!????"

Mulroney also shared other images from the event on Instagram. 

"When @kiefersutherland says "never had more fun on a movie" #youngguns you know@you had some fun !" the star captioned his post. He also included a nod to the iconic movie with the hashtag, "#didyouseethesizeofthatchicken."

In the images, the men looked like they were having some fun. The final picture in the carousel of images was the cast of "Young Guns" flipping off the camera and smiling.

Due to the original film's success, a sequel titled "Young Guns II" was released in 1990, directed by Geoff Murphy. This follow-up picks up later in the timeline as an aging Brushy Bill Roberts claims to be an elderly Billy the Kid, recounting the dramatic final days of the surviving Regulators — primarily Billy, Doc Scurlock and Chávez y Chávez — while they are hunted down by their former friend-turned-lawman, Pat Garrett.

The sequel expanded its cast with new stars like Christian Slater and Alan Ruck, and it achieved massive pop culture success largely thanks to its iconic, Academy Award-nominated theme song, "Blaze of Glory," written and performed by Jon Bon Jovi.
