Swedish media are reporting that more than 10 studios, including Disney, Warner Brothers, Colombia Pictures and Universal, have filed papers at Stockholm District Court demanding that the site be shuttered.
The Pirate Bay hosts no copyright infringing material itself but does host links to the location of files, many of which are infringing copies of media such as songs, television programmes and films.
Site administrators Fredrik Neij, Gottfrid Svartholm Warg, Peter Sunde and backer Carl Lundstrom were sentenced to a year in prison and fined a collective £2.5 million in April.
"We’ve been forced to seek a court order demanding that they stop the spreading of … roughly 100 films and television programmes," the firms' Swedish lawyer Monique Wadsted told Sweden's English-language news outlet The Local.
"[The four convicted men have] been sentenced to prison for criminal activities but haven’t stopped carrying out those activities," Wadsted said. "What matters is that the spreading of these works is stopped."
The court action requests the serving of an injunction to stop the operation of the site.
It was announced last month that The Pirate Bay would be bought by Global Gaming Factory (GGF) and turned into a legitimate file-sharing site, but that deal looks to be in jeopardy this week.
The company, run by Hans Pandeya, had agreed a $7.8 million purchase of the domain name and web sites belonging to the organisation, but the departure of a senior executive recently hired to work on the new site has raised questions about the deal.
Wayne Rosso, who was once president of peer-to-peer technology company Grokster, has reportedly walked away from his recently-created role at The Pirate Bay.
He told CNET News that he had "very strong doubts that the funding is in place [and that] there are other issues regarding Mr Pandeya's credibility that trouble us greatly."
Last week a lawyer for GGF told a Dutch court hearing a copyright infringement case that the deal is conditional on the company's ability to turn The Pirate Bay into a legitimate business.
