COVID-19, Sean Penn has reiterated his comments in a new interview, saying he thinks vaccination should be “mandatory”.Earlier this month, the actor and filmmaker made his position clear at the premiere of his new film Flag Day, at which the audience were required to wear masks during the screening and provide proof of vaccination.“I have to say that I do request people who are not vaccinated, don’t go to the cinemas,” Penn said. “Stay home until you are convinced of these very clearly safe vaccines.”A month earlier, Penn made headlines for refusing to return to the set of his upcoming film Gaslit until everyone on the production had been vaccinated.
