There he teams up with Vasu (Goundamani) and they come up with an ill-advised plan to kidnap Indu (Rambha), the daughter of Vishwanathan (Manivannan). Vishwanathan is in fact Col.

The film was a success at box-office. Balaji wrote:" It stands out in that every aspect of it, be it the romance or the fights, has been handled with an eye on comedy and there is not a single moment of emotions or sentiments".
The success of the film paved way for numerous comedy films. The film made Sundar C. as one of the most sought directors. Rambha gained popularity through this film and became one of the leading heroines. The film also made Manivannan as one of the famous comedians. Karthik and Goundamani became one of the famous comic pairs from the film, the pair went on to do many films. The success of the film led Sundar C. to collaborate with Karthik in subsequent projects - Mettukudi (1996), Unakkaga Ellam Unakkaga (1999) and Azhagana Naatkal (2001). Azhagana Naatkal was compared by critics with Ullathai Allitha due to its similarity in sequences and characterisations.
Sundar C. himself listed it as one of the favourite films he had directed. Vimal who acted in director's Kalakalappu recalled that he had watched this film during his schooldays. Subha J. Rao and K. Jeshi of The Hindu placed the film in league with other successful comedy films like Kadhalikka Neramillai (1964), Thillu Mullu (1981) and Michael Madana Kama Rajan (1990).
