Welikathara (Sinhala, වැලි කතර), is a 1971 action thriller drama film made by Sri Lankan director D. B. Nihalsinghe.

[2] Since Welikathara was the first film in CinemaScope in Sri Lanka, it faced many obstacles, first of which was the lack of access to cinemas capable of showing that format.

D. B. Nihalsingha went on to direct several other award-winning films, Ridi Nimnaya, Maldeneiye Simieon and Kelimadala, before he went on to pioneer color television production in Sri Lanka and South Asia.

[2] Gamini Fonseka, who was Sri Lanka's foremost star at that time, gave a significant performance where, in a total reversal of the heroic roles he portrayed, he acted out a character in decline.

Somadasa Elvitigala added one more feather to his cap with this film after the beautiful musical score he created for Sath Samudura.
