prithviraj goes to great lengths when it comes to essaying the characters of his movies with perfection his upcoming movie vimaanam directed by pradeep m nair could prove the toughest yet as it will have the actor playing a differentlyabled mechanic piloting an aircraft 800 meters above sea level the director tells us vimaanam is an inspiring tale of a man achieving his dream despite all odds prithviraj plays a differentlyabled youth who drops out of school after his predegree to build an aircraft that he can fly however the director is quick to clarify that though the main character is physically challenged the film is not based on the reallife speech andhearingimpaired hero saji thomas who built an ultralight aircraft all by himself pradeep says this is a fictional story and only a few portions have been inspired from sajis life prithviraj will not be seen as a hearingandspeech impaired protagonist and vimaanam is a musical love story he is a desi mechanic of sorts i dont want to reveal more about his character right now it was earlier announced that the team would be building three ultralight aircrafts exclusively for the movie with the help of saji we have imported the parts required for the aircrafts and they should be ready soon says pradeep adding that the movie will have a lot of aerial shots with prithvirajs character flying the aircraft last year the actor had got a deepsea diving expert certification to film the underwater scenes for anarkali so will he be flying the plane in real flying is not as easy as diving you need 40 hours of flying experience to get a pilot license for an ultralight aircraft but prithviraj is very much involved in the technical side of the project the team is planning to begin filming the movie by the end of july it demands extended preproduction as a lot of visual effects are involved to film the flying sequences also we need permission to shoot at various locations says the director
