I can't accurately predict when Xie Wendong can be made into a movie or TV series. Xie Wendong is a fictional character whose story and background are in online novels, so whether it can be adapted into a movie or TV series depends on the wishes of the author and copyright owner, as well as the choice of the relevant film or TV production company. If the author and copyright owner decided to adapt it into a movie or TV series, a series of approval and negotiations might be needed to ensure that the adaptation was legal and in compliance with relevant laws and regulations. Therefore, I suggest we wait and see if the author and copyright owner are willing to adapt it into a movie or TV series, or if there is any other relevant information for reference.
