The highest crane shot ever done for a feature film was done on 13 October 2003 with a 24ft Giraffe crane at 17.796 ft above the Tanglangla Pass (17582 ft) in Ladakh, India.
The vast majority of the non-speaking Army roles in the film were filled by real-life soldiers of 13th Battalion, The Punjab Regiment. (In the film, the unit portrayed is 3rd Battalion, The Punjab Regiment.)
When Director Farhan Akhtar went back to Indian Military Academy after 15 years. 70% of the gentlemen cadets told him , they joined Indian Military Academy after watching Lakshya.
Pankaj Tripathi stated " I also did Lakshya, again around the same time. In fact, the first time I gave an audition was for Lakshya. I was cast for the role of a character named Subedar Kuldeep Singh. I visited Leh-Laddakh for the first time during its shooting only. Before the release of the film, I was in Patna. While talking to one of my media friends there, I randomly mentioned that I am a part of it. He got excited and asked more details. I told him about my role and about my scenes with Hrithik (Roshan). Next day news was out in the Hindustan newspaper in Patna with the headline "Lakshya mein dikhega Bihar ka laal" along with a small picture of mine. Then I went to watch Lakshya at Ashok cinema hall there along with my wife. The entire film got over and I was nowhere to be seen. My agony doubled, not because I have been edited out, but because this news had already been published in the newspaper. I was so tensed up. If the news wasn't out, I wouldn't have felt so much pressure. I thought now whoever will read it will take me as a liar, since I work in a medium which has lie as its base - we have fake son, fake mother, fake relationships, fake stories... But I try my best to make it look real. I never asked Farhan Akhtar about it. While working on Super 30, Hrithik and I did have a small chat on it. Hrithik asked me whether Super 30 was our second film or the third one. He only remembered Agneepath. I reminded him of Lakshya too.".
This film portrays a fictionalized account of the actions of 3 Punjab. As the film shows, 3 Punjab was based in Kargil and was among the first of the units to detect the Pakistani intrusion across the Line of Control; however, they did not actually capture "Peak 5179" or any other peak. Much of the on-screen unit's actions are inspired by the actions of various other battalions during the conflict. As the film credits the story as fiction based on fact and is largely truthful to the overall situation, the Army officially endorsed and approved the film.
