Superstar Amitabh Bachchan always keeps his commitment. On Thursday he was about to launch a book but couldn't as he is suffering from high fever.

However, he wrote an apology letter to organizers. A letter of apology has been sent to the organisers by Big B.

The letter read as: "I have suddenly and quite unexpectedly developed a high fever .. I regret profusely that I shall be unable to attend your event this evening .. a shame really because I was looking forward to it .. "As a country we have shied away from the luxury of documentation.. leave alone its restoration and preservation - for films at least ..!! "What you and your foundation have initiated is indeed a most selfless, but very important and necessary element, so assiduously worked upon by Mr Nair .. "I send my best wishes on the launch of your book on him and do stand by my commitment to be of service to this noble cause. "Your idea of constructing an Institute, the design for which I have greatly appreciated, is most laudable and one that I hope shall receive patronage not just from the film fraternity but indeed from the City of Mumbai - the Film Capital of the Nation .."
