The similarity of story lines of both the movies:

In “Little Boy,” Pepper, the protagonist, often finds himself amid constant bullying for his short height. However, he never lets that come in the way of his mission to tracking down his father, who went missing in a war.  In “Tubelight,”rumours are around of Salman playing the titular role. He is someone who is a slow learner and has a tough time picking up hints. Despite the shortcomings, the character sets out on an unimaginable journey to find his brother (Sohail Khan), but not without some help from onscreen love interest (to be essayed by Zhu Zhu).
