The Star Wars and Indiana Jones actor will be honoured for his hugely successful career in Hollywood at the annual film gala in Switzerland on October 4, reported Contactmusic.

'Harrison Ford has had one of the most remarkable careers of any actor in cinema, helping to propel two of the greatest movie franchises by bringing to life iconic roles that have become just as famous as the films themselves.

Argo star Ben Affleck had a fair idea that his casting as the caped crusader in the Man of Steel sequel might spark a controversy, but he remained indifferent because he calls himself a tough guy.

The 41-year-old actor, who replaced Christian Bale as Batman in the untitled Batman-Superman movie, received heavy criticisms after the casting news with fans even launching an online petition demanding Affleck's replacement, said the Hollywood Reporter.

'They called me up and said, 'Do you wanna do this?' And I thought, 'Well, I'm not 25, man. Are you sure about this?' Affleck said.

After the actor discussed the film with director Zack Snyder, he agreed to star as the new Bruce Wayne in the sequel.

However the executives had warned him about the criticisms to ensure he knew what was at stake.
