The two actors will start shooting in Hungary's capital for their upcoming film Force 2 (a sequel to the 2011 Force) from September 5.
Last night, Abhinav Deo, who will direct the film, left Mumbai to set the stage for the shoot.
The cast and crew is expected to return in the third week of October.
A source close to the film says, "We will shoot almost the entire film in Budapest. There's only a very small part to be shot in Mumbai, which we will complete after we return."
Force was directed by Nishikanth Kamath and shot mainly in Mumbai. Genelia D'Souza played the female lead opposite John.
Vipul Shah, who produced the first part, will produce the second as well.
