The 62-year-old star of Notting Hill and Love Actually confessed he had to do a lot of grovelling after losing his temper with a child's chaperone.
Grant told Total Film magazine: "I lost my temper with a woman in my eyeline on day one. I assumed she was some executive from the studio who should have known better.
"Then it turns out that she’s an extremely nice local woman who was the chaperone of the young girl. Terrible. A lot of grovelling... "
Grant was referring to The Dark Knight star who famously apologised in 2009 after a tape was leaked of him launching a foul-mouthed rant at a member of the film crew on set of Terminator: Salvation.
Bridget Jones Diary star Grant has a reputation for losing his temper.

In 2012 The Daily Show host Jon Stewart called Grant "the worst guest" he had ever had on the chat show and said he had banned him from ever coming back.
Stewart said: "He’s giving everyone s**t the whole time, and he’s a big pain in the a*s."
Grant later told Vanity Fair: "I did have a tantrum backstage. About once a year, I have a really mega-tantrum, and sadly he witnessed one."
Grant stars in the new live action film of hit role-play game Dungeons and Dragons with Chris Pine and Michelle Rodriguez.
