There are few movies that can be termed as an icon and a model to other movies. In fact there are really very very few. Thiruvilayadal makes it to the top of that list.
There are various reasons for making that statement. I am saying this because, the year 1965 was not an era when India could use the latest technology that was available with the rest of the world. The resources were limited and in spite of that, coming out with a movie like this makes it a world class.
The graphics are outstanding. I try to compare with the Ramayan that was shown in the 80s and Thiruvilyadal still beats it. The color is so rich and suits the mythological mood.
About the Music, I do not have words to express its beauty and melody. Every song is a gem. "Phazam nee appa" is a song that will stand as a testimony to the Carnatic music and devotional song for years and generations to come. The "Pattum Naane" song is another gem. To sum it up, all the songs put together makes an exquisite ornament for the movie.
Sivaji as Lord Shiva is a perfect suit. How did they do the casting? I get goosebumps thinking of all this. I read somewhere that after watching this movie, some people thought that Lord Shiva would look like Sivaji. I would definitely agree.
Nagesh makes that fine garnish to the movie by providing that perfect humor and not taking away the essence.
In all, this movie is a must watch and should be in your collection if you own movies. I have enjoyed this movie, its language and the songs and all this being a non-Tamil. I would recommend that everybody should watch this movie at least once to understand the craftsmanship our movie producers (actors, music directors, singers, technicians) had many decades ago.
