The common factor for all these films is its production house, 14 Reels Entertainment. Going by the trend, it is pretty obvious that Mahesh is on a signing spree with this house exclusively that is owned by three partners. Sources from within the industry circles speculate that Mahesh owns a certain stake in this production house and hence the liberty to sign their projects on a continuous basis. This despite the fact that there are many other producers waiting in line since a long time to get his dates for their movies.
Looks like Mahesh is also a heck of a businessman aside being a wonderful actor.
