The film was shot entirely on an iPhone in Kerala, India between May and July 2020 during the Covid-19 pandemic.
Kerala Film Producers Association (KFPA) was opposed to the shoot with regards to the disruptions caused by the COVID-19 pandemic. Despite this, filming was successfully completed on August 21 2020.
'C U Soon' is based on a true incident and also a small inspiration of the Hollywood movie 'Searching(2018)'.
"C U Soon" is India's first computer screen film.
