It's a well-known fact that Tamil stars have a huge fanbase in not just Tamil Nadu but also the neighbouring state of Kerala. Tamil films take huge openings in the state and enjoy a good run at the box-office too.
In fact, a recent Malayalam film Pokkiri Simon with Sunny Wayne in the lead role was about Vijay fans in Kerala. Several Malayalam films have references to Tamil popular culture, especially film songs.
An episode of Comedy Utsavam aired on Flowers TV recently saw a Kerala Vijay fan imitating the Tamil actor perfectly. Malayalam star Jayasurya, who'd come as one of the judges, was stunned by the performance.
The Vijay fan was accompanied by another mimicry artist who imitated actor Santhanam (although he's a specialist in mimicking actor Vishnu Unnikrishnan). Together, both of them did "spot dubbing" for a comedy scene from the Vijay film Thalaivaa in which the two men appear alongside Amala Paul. From the dialogue delivery to the pauses, the mimicry artist was spot on. Jayasurya told the artist that he must consider dubbing for films in future.
Following Jayasurya's request, he went on to mimic Vijay's Malayalam dialogues from the film Theri, in which the actor says he's Joseph Kuruvilla. It's pretty amazing to watch the Malayali young man imitating Vijay speaking Malayalam with a Tamil accent. The dialogues were so perfectly rendered that Jayasurya looked visibly gobsmacked.
The art of mimicry is very popular in the state of Kerala and actors like Jayaram and Dileep got into the industry by performing as mimicry artists. Many stars from the industry have appeared on the show previously. Comedy Utsavam is anchored by Mithun Ramesh.
