It is very known to all that Action King Arjun is an ardent devotee of Lord Hanuman. The actor has built a temple for Lord Hanuman on which he have been working from quite sometime now.
He was on a hunt for this sort of monolith rock for nearly a year and it took him nearly four years to sculpt it. Artisans from Hubli have worked on it. The idol was built out of a single rock. The moonlight is constituted of a rock which was sent to his farmhouse in Chennai from Karnataka. It's said that the idol within the temple is as tall as 35 feet and has the God in a padmasana pose. Reportedly that is the primary Hanuman idol on the planet on this pose!

Thousands have gathered at Gerugambakkam, a village in Sriperambudur to catch a glimpse of the idol. The temple might be ready in a year so one can be followed by a kumbhabishekam.
Incidentally, Arjun played the role of Lord Hanuman in 'Sri Anjaneyam', a 2004 Telugu blockbuster.
