As of August 2011, the film has been hit with two lawsuits and, according to Catfish distributor Relativity Media, the film has an unrecouped balance of more than $8.5 million and will not likely ever become profitable. Both of these lawsuits have to do with songs used within the movie not being attributed to their creators.
The song "Megan" sends to Nev titled "Truman Sleeps" is actually from the movie The Truman Show (1998).
As of 2023, the Google Street View image shown in the movie (of the Wesselman house with a child playing in the yard) is still the official image on Street View for that address.
