The Redwood Sap is the 36th animated cartoon short subject in the Woody Woodpecker series. Released theatrically on October 1, 1951, the film was produced by Walter Lantz Productions and distributed by Universal International.
- There is no director's credit for this film. Lantz himself has claimed to have directed The Redwood Sap, but does not receive on-screen credit.
- Some animation and sound effects came from earlier Woody films. The scene of Woody walking away from the screen at the tail end was recycled from Puny Express. Also the "Starvation" personification was recycled from Pantry Panic and Who's Cookin' Who?, and the audio of his spooky laugh was also recycled from Who's Cookin' Who? (as done by former storyman/voice actor Ben Hardaway).
- Woody has no dialogue in this film, while the other animals "dialogue" was sped up and is almost unrecognizable.
