During the dance scene of bole chudiyan, one sleeve of Hritik Roshan's dress almost got fully tore in a very fast sequence which is easily not visible and in the subsequent scenes his clothes are fully perfect.

When Hrithik and SRK are driving in the silver Mercedes, SRK can be seen wearing a pair of sunglasses. In the immediate next shot, he isn't wearing them and proceeds to wear them after Hrithik puts on his sunglasses.

When Anjali's son performs the Indian National Anthemn impromptu at an English school function, the crowd automatically stands to attention as a sign of respect. However English people are largely unfamiliar with the Indian National Anthemn so would not have understood it's significance.

The film, as narrated in the flashback, was set in 1991 but at his birthday party, Amitabh Bachchan was seen dancing to the song Aati Kya Khandala, from Aamir Khan's film Ghulam, which only released in 1998.

Okay then! Hrithik Roshan arrives in Bebo's college in a red convertible, Lamborghini Countache, making everyone drool. But in another scene, when he was seen with SRK, his ride changes to a silver Mercedes.

Poo can do anything, you see! In her first scene, she steps out of the house wearing this sexy strappy number, and immediately, out of nowhere, the jacket comes out. Weather change, can't help.

Kareena Kapoor Khan leaves the house for prom night wearing mismatched pair of heels and calls it "fashion", but soon after, she ends up in perfectly matched red stilettos when she reaches the club!

After Hrithik comes to stay at SRK's home in England, one morning Hrithik gives a lift to SRK to his office as his car tire is punctured. On the way, they put on a match commentary.

Years later when Rohan meets Pooja again, after he recites the tongue twister "Chandu ka Chacha," he says he finally got it. But he forgets to say the line "chandni raat mein," so he doesn't get it right.

The trend-setting Pooja's nickname at her English school is 'Poo', a name that would've bought her much ridicule rather than idolization, as the word 'Poo' is everyday English slang for excrement.
