'There were many attempts by both of us to work together but somehow it didn't work out,' Amitabh posted on his blog www.bigb.bigadda.com.
'He will be remembered for his passion and commitment to the craft. May his soul rest in peace and may the Almighty give his family strength to bear the loss,' he added.
The flamboyant actor-filmmaker died Sunday at his farmhouse in Bangalore after battling cancer for a year. He was 69.
Amitabh describes Feroz Khan, who made hits like 'Dharmatma' and 'Qurbani', as a flamboyant filmmaker.
'A flamboyant filmmaker, one that in the middle of his acting career became a producer and director and gave us some very memorable films - all with a certain stamp of flamboyance.
'What he displayed in his persona, reflected in the way he made his films. In many ways, he pioneered a certain flash and sophistication in his very first venture as a maker and that remained with him and all his films throughout,' he wrote.
Amitabh also pointed out that Feroz Khan always had a 'progressive and visible difference in the way he functioned' including the 'content of the subjects he chose, in the unique casting that he did or in the fresh talent that he introduced in music and presentation'.
Amitabh recalled the recent Stardust award function where Feroz Khan was given the Stardust Pride of the Industry award.
'In a most poignant moment, his son Fardeen had received it on his behalf from Jaya (Bachchan) on stage - Feroz being too ill to be present,' he added.
