Continuity mistake: The V that Tyler spray paints on the church wall becomes significantly thicker when they show it a second time, as he is running away from the priest who finds them.
V (2009)
1 continuity mistake in Unholy Alliance - chronological order
Starring: Morris Chestnut, Elizabeth Mitchell, Joel Gretsch, Logan Huffman
Factual error: Early in the episode, it is mentioned that Mrs. Faulkner's husband flew an F-16 fighter. Later, during Mrs. Faulkner's speech after her meeting with Anna, a picture of her husband is shown. He is wearing a Navy Dress Blue uniform. The Navy does not fly F-16s. In the US military, they are used exclusively by the Air Force.
Trivia: Morena Baccarin plays the mother of Laura Vandervoort. In real life, Baccarin is only five years older than Vandervoort.
