Sir Brian Pitman, the interim chairman of ITV, is reported to be meeting a number of institutional investors, who want an explanation for the huge payout Green won as a result of his ousting as chairman of Carlton last year.
Investors were furious about the size of the payoff, which saw Green pocket £13.2m in shares and £1.8m in cash. Their anger was increased by the fact that Green had no formal contract with Carlton despite having been there for 20 years.
In justification it is thought that Sir Brian will tell the investors that the award was not a "pay-off'" and was less than asked for, according to the Financial Times.
Sir Brian's defence of the payment could decide the fate of Carlton remuneration committee executives, John McGrath and Etienne de Villiers, who along with Sir Brian authorised the payment.
"Let's just say we will have some pretty interesting questions to ask Sir Brian when we see him this week," one major shareholder told the Daily Telegraph.
As well as the payment to Green, the three also gave the go-ahead to a further £12m of payments to two other Carlton directors, Paul Murray and David Abdoo.
Green is again working with Murray, who was Carlton's former finance director, and Abdoo, its former company secretary, on his bid for UCI Cinemas.
Some investors are known to want to see the heads of Murray and Abdoo roll, although it is thought unlikely that Sir Brian too will get the axe.
His role is seen as more vital as he prepares to hand over the reins to the newly appointed chairman, former chief executive of Bank of Scotland Sir Peter Burt, who takes up his role next week.
