Hrithik Roshan's sons Hrehaan and Hridhaan are helping grandpa Rakesh Roshan in writing Krrish 4

So we get a pretty fresh take on the superhero saga this time…

Rakesh Roshan is currently writing the story of Krrish 4 and guess who’s helping him with it — his grandsons 10-year-old Hrehaan and eight-year-old Hridhaan! The two children have been actively participating in the developments of the storyline, which revolves around the adventures of superhero Krrish (Hrithik Roshan).

Rakesh Roshan, Honey Irani, Robin Bhatt, Sachin Bhowmick and Akash Khurana, who have all written for the earlier installments in the franchise — Koi Mil Gaya, Krrish and Krrish 3 — are on board for the next, Krrish 4, which Roshan Sr plans to launch next year.

Says a source, “Rakesh likes to make his films stylistically, as close to Hollywood as possible. He was the first to develop Krrish as a superhero franchise, but today, superheroes are no longer as simple as they used to be. His grandsons —Hrehaan and Hridhaan — are huge fans of science fiction and action movies like Batman vs Superman, The Jungle Book, Captain America: Civil War, Spider-Man, etc. They are not just computer-savvy, but also know what they like. So whenever he sits down to write, he calls them over and they have brainstorming sessions over the story. The children fill him in on what’s new, what’s hot, what’s not, etc. The filmmaker knows that by the time the film releases, more developments would have taken place, so he wants to be well-equipped. The children state their minds clearly and Rakesh incorporates their vision into his story.”

Rakesh Roshan had revealed in 2013 that he would soon start working on Krrish 4 and had promised to include some sidekick characters in the upcoming film. Buzz is, Krrish 3 villain Kaal (Vivek Oberoi) will make his comeback in the film.

Hrithik Roshan is a pretty doting father. We’ve seen the way he absolutely adores spending time with his sons, Hrehaan and Hridhaan. In fact, the Mohenjo Daro star makes it a point to takes a relaxing break in between projects so he can enjoy some family time with them. And the vacay getaways have become a regular for the Roshans. If you remember, last year Hrithik took his sons to Miami for a short trip and also visited the Cape of Good Hope in South Africa. And again, this year they decided to have some more of adventure as they went to Africa. Right after IIFA 2016, that was held in Madrid, Spain, Hrithik took his babies to witness the wilderness in Africa by taking them to Mount Kilimanjaro.
