The company is considering options including a full or partial sale to another private equity firm, one of the people added.
In the event of a sale, the business could be valued at more than 500 million euros, this person added.
Deliberations are at an early stage and a sale process may not occur, said the people, who declined to be named because the talks are not public.
Montefiore and Federation Studios declined to comment.
A sale process for Spanish broadcasting and sports rights group Mediapro is also underway, according to Reuters.
