"It will take me a day or two to contain my amazement. I am stunned to see that our country can also make films with such finesse and superior technique," the 68-year-old said here Thursday at a special screening of the film.
"The techniques and special effects in the film are not less than any international film," he added.
Javed applauded director Rakesh Roshan calling "Krrish 3" a director's film.
"It is a time of good movies and it is a good film. I congratulate Rakesh Roshan, it is truly a director's film. The way he conceived it and made it, is wonderful," Javed said.
