Siddique-Lal are a screenwriter and director duo, consisting of Siddique and Lal. They were active together in Malayalam cinema during 1989–1995. Particularly known for making films in the comedy genre, the films that came out of the partnership include Ramji Rao Speaking (1989), In Harihar Nagar (1990), Godfather (1991), Vietnam Colony (1992), and Kabooliwala (1993). All of these films were some of the biggest hits in Malayalam cinema and many of them have a cult following in Kerala. The duo broke off in 1993.
After the breakup in 1993, Siddique continued his career as a director while Lal turned into acting, later began producing the films he acted in, and then established himself as a notable actor, producer and distributor in Malayalam film.
Siddique later directed Hitler (1996) and Friends (1999) for Lal's production house Lal Creations. After sixteen years, Lal did come back as a director by directing the sequels to In Harihar Nagar, 2 Harihar Nagar (2009) and In Ghost House Inn (2010).
