Director and writer Rasmus Merivoo revealed in Tulnukas 2, Rasmus Merivoo (2024) that Uku Uusberg was not able to reprise his role as Rait due to other commitments, namely being the artistic director for the XIII Youth Song and Dance Celebration and at Tallinn City Theatre. The role of Rait was recast, with Tõnn Lamp portraying him in this sequel.
"Karvaste sauna" is actually Rasmus Merivoo's former Chemistry teacher Jüri's sauna. Jüri also had a role in the first part, where he jumped into the pond where Valdis urinated.
In Tulnukas 2, Rasmus Merivoo (2024), director and writer Rasmus Merivoo said of this movie that the first half is a conservative's nightmare and the second half is a liberal's nightmare.
The beloved patriotic song "Koit" was used in a controversial scene near the end of this movie. In Tulnukas 2, Rasmus Merivoo (2024), director and writer Rasmus Merivoo mentioned that he had wanted the song's author Tõnis Mägi to see the footage before proceeding, but due to scheduling conflicts, the two never met. However, Mägi did his own research about Merivoo and felt such kinship that he was comfortable enough to allow the use of his song without seeing the scene. Interestingly enough, Tõnis Mägi's son-in-law is Märt Avandi who portrays the lead role of Valdis.
