Allaah has indeed praised the sahaabahs and manifested their elevated status. Hence, by depicting the life of any of them, either by means of theatrical plays or cinematic acting, negates this honour that Allaah has bestowed upon them. 

Narrated by Jaabir ibn ‘Abdullaah,

The Messenger (sallallaahu 'alayhi wa sallam) said on the day of the battle of Uhud, “Who saw the killing of Hamzah?” So a man who was by himself said, “I saw his killing.” He said, “Let’s go and show him to us.” So the Messenger (sallallaahu 'alayhi wa sallam) walked until he saw Hamzah and stopped; his stomach was gouged and he was mutilated. So they said, “Yaa Rasoolullaah, they mutilated him, by Allaah.” Thus the Messenger (sallallaahu 'alayhi wa sallam) did not want to look at him. He stood in the middle of those who were killed and he said, “I am a witness for them, bury them in their blood (i.e. do not shroud them) for indeed there is no one who is injured in the path of Allaah except that on the day of judgment his blood will gush forth and its will the colour of blood and its smell will be the smell of musk. Bury those who know the most Qur’aan first.
