Did will smith improvise the father scene on fresh prince? And is it because his father left him that it was so sincere?

Yes, Will Smith improvised his dialogue for the very emotional ending of “The Fresh Prince of Bel-Air: Papa's Got a Brand New Excuse” (1994), which was not scripted. Smith thought the cameras had stopped rolling when he said "How come he don't want me, man?"

Smith's own father served in the U.S. military and demanded that he should live a structured and focused life. Smith says this upbringing has driven him to have a certain "obsessiveness" to his career and to the goals he is trying to accomplish. Read more about Will Smith's father at Metro.

In this episode, Will's father Lou shows up after fourteen years and spends a lot of time with Will. Will's very pleased, but his uncle Phil thinks Lou will again disappoint his son. This episode had very few jokes, as it focused more on an emotional build-up.
