The Long-Forgotten '50s B-Horror Movie That Marked Clint Eastwood's Official Big Screen Debut: 'Revenge of the Creature'

With the benefit of hindsight, it's easy to associate Clint Eastwood with his career-making performances in his numerous Westerns over the years.

Like fellow industry giants John Wayne or Gary Cooper, Eastwood helped redefine the entire Westerns genre for generations, as seen through his iconic work on films like The Good, the Bad and the Ugly, A Fistful of Dollars and Unforgiven.

While closely recognized for his achievements within the larger Western genre, it's interesting to note that Eastwood's first on-screen appearance came courtesy of a little-known B-horror movie that earned almost universally negative reviews.

At the time of its release, 1955's Revenge of the Creature acted as a direct sequel to Universal's far better-received Creature from the Black Lagoon. While most viewers have long since forgotten the movie, Revenge of the Creature remains most notable today for the early appearance of Eastwood, who briefly appears as an uncredited lab tech in the film.

Though it's far from a substantial part, Eastwood does hand in a humorous enough moment as the absent-minded technician, right down to the moment he pulls a live rat from his lab coat after claiming to have lost the animal during an ongoing experiment.

The year 1955 proved an exciting year for the then 25-year-old Eastwood. The same year he appeared in Revenge of the Creature, the young actor also appeared in a string of movies, including Francis in the Navy, Lady Godiva of Coventry and Tarantula.

That same year, he also appeared in two different TV projects, starting with the TV movie Allen in Movieland and an episode of Highway Patrol. Of course, the actor's big break came courtesy of the wildly popular Western TV series Rawhide just a few short years down the line.

After appearing in the main role of Rowdy Yates for six years on the series, Eastwood managed to successfully transition back to a full-time role in film, eventually landing a starring role in the influential Western, A Fistful of Dollars.
