While the character of King Arthur is credited to Emma Rombold, due to sickness and poor planning the for the last half of the movie the character is played by Margo Smith, however, Margo does such a good impression of Emma's King Arthur that it is next to unnoticeable in the final product.
English The Move: 4Ever After is the first movie of Evan's Production to include a fully white cis allo straight male character. This was met with backlash from some of the producers, saying that it was unbelievable that a character could be both European American and straight, much less cis and allo as well. Despite this, Jack Mularski, the writer, campaigned for this, knowing several people like this, and eventually won over the studio execs, allowing him to include a scene where Banquo comes out, inside of a Buc-ees (which was cut out for foreign audiences). However, many people have said that this scene feels weaseled into the screenplay and was "forced diversity".
The main writer, Jack Mularski, wrote the entire movie in two months to get out of taking a final exam for his English 4 class.
