Fans are remembering late actor and former child star Jonathan Brandis on what would have been his 45th birthday. Famous for his many roles as a child actor including Ladybugs, Sidekicks, and the It miniseries, Brandis was one of the breakout stars of the 1990s who still had an entire life left to live in front of him.

Taking to Twitter, many are expressing their thoughts on Brandis and how the pain of his death still hurts all these years later.

There's any number of roles fans of Brandis might remember him from the most. He'll always have a place with horror fans due to his role as the young Bill Denbrough in Stephen King's It miniseries. For his role as Lucas Wolenczack on seaQuest DSV, he found even greater fame by winning the Young Artist Award in 1994. A teen idol whose face adorned scores of magazine covers at the time, Brandis was one of the most recognizable young stars of the era.

On the movie side, Brandis scored his first starring role in the 1990 sequel The NeverEnding Story II: The Next Chapter. He also co-starred with Chuck Norris in the highly memorable action-comedy movie Sidekicks in 1992 and worked with legendary comedian Rodney Dangerfield that same year on the soccer movie Ladybugs. One of his final roles came in the 2002 drama Hart's War, though his scenes were drastically reduced for the theatrical cut.

Just recently, Brandis returned to the spotlight when he posthumously appeared in the Hulu documentary Kid 90. Directed and produced by Punky Brewster star Soleil Moon Frye, the movie follows the young actress as she carried a video camera around with her in the 1990s. Brandis was among many other stars of the 90s who appeared in Moon Frye's footage, appearing alongside other names like Mark-Paul Gosselaar, Stephen Dorff, Corey Feldman, Leonardo DiCaprio, and Sara Gilbert. The movie is now streaming on Hulu.

Happy heavenly birthday to Jonathan Brandis. The acting legend might be gone, but it's clear from the fan tributes on what would have been his 45th birthday that he will never be forgotten. May he continue to rest in peace.
