The awards, presented by the Academy of Science Fiction, Fantasy and Horror Films, will be presented July 26 in Burbank. The academy was created in 1972 to recognize films overlooked by mainstream awards.
Oz and Remar will both receive the academy's Life Career Awards.
Oz rose to fame alongside Muppets creator Jim Henson, and as a performer gave life to characters such as Miss Piggy and Yoda of "Star Wars" fame. He also directed films including "The Dark Crystal," "Little Shop of Horrors" and "Dirty Rotten Scoundrels."
Remar appears on the Showtime hit "Dexter," and has also been seen in shows such as "Sex and the City" and "Jericho" and films such as "48 Hours" and "The Cotton Club."
Kirkman will receive an Innovator Award for his work on the blockbuster horror series "The Walking Dead," which academy officials called a "mix of genuine horror, unrelenting suspense and captivating drama."
"The Simpsons" will receive the Milestone Award, recognizing its status as the longest-running animated program in television history, the longest-running sitcom on American television and longest-running prime-time scripted series.
Filmmaker Martin Scorsese, director of the nominated film "Hugo," was previously announced as the recipient of the academy's Visionary Award, although he will not be able to attend the July ceremony and will be honored at a later date.
