Originally released as a weekend "kiddie matinee" feature, the film was rediscovered and re-released on DVD in 2004 by Something Weird Video, and has subsequently gained something of a cult following for its low budget production values, as well as for the unintentionally camp performances by the adult character actors.

The film opens by a lake on Saint Patrick's Day as the story's young hero, an Irish boy named Matthew O'Brien (David Alan Bailey), is playing hooky from school and fishing with his best friend, Timothy Ryan (Ernest Vaio).

Deciding to take a short-cut home through the woods, Matt quickly finds himself lost and soon encounters a leprechaun (Frank Delfino) whose beard is caught in a log.

As Matt becomes desperate to find his way home, he unintentionally spends his first coin wishing for some guidance, which, to his surprise, brings a long suffering wooden sign post to life.

Grateful to Matt for freeing him, Sir Humphrey warns the boy to avoid the Wicked Wizard who had placed him under a spell while he was attempting to rescue a princess named Cecilia.

Sir Humphrey decides to accompany the boy as he searches for a way out of the enchanted forest, but their plans are interrupted when the Wicked Wizard (G. Edward Brett) suddenly appears in a cloud of smoke and banishes them to a barren desert.

"[9] The "kiddie camp" connoisseurs at KiddieMatinee.com described the film writing, "The Princess and the Magic Frog (1965), produced and released originally as At the End of the Rainbow, is a fascinating (albeit threadbare) U.S. fantasy film, very much in the spirit of similar mid-1960s Kiddie Matinee indie product such as Santa Claus Conquers the Martians, The Magic Christmas Tree and Jimmy, the Boy Wonder.
