"The entrance hall was so big you could have fit the whole of the Dursleys’ house in it. The stone walls were lit with flaming torches like the ones at Gringotts, the ceiling was too high to make out, and a magnificent marble staircase facing them led to the upper floors."
—Description of Harry's first view of the entrance hall[src]
The Entrance Hall's description from the books is brought to life in the video game adaptations of Sorcerer's Stone, Chamber of Secrets and Prisoner of Azkaban, where it's a vast room with a large marble staircase and the House Point hourglasses. The later games use the smaller room from the films and relocate the hourglasses to the staff end of the Great Hall.
In the first two films, the Grand Staircase is not directly left of the Great Hall. It was to the left then to the right of the Great Hall. This can clearly be seen when in the second film Nearly Headless Nick enters the Great Hall from the left and the Grand Staircase can clearly not be seen.File:37812 332327540197872 1451691755 n.jpg
Entrance Hall and the corridor
In the first two films, there is a gold statue of the Architect of Hogwarts in front of the window across from the stairs. This statue isn't seen in the third and fourth films but re-appears in the fifth and the sixth. This statue also appears in the fifth and sixth video games. The statue then replaced by the statue of the First Headmaster of Hogwarts.
In the Harry Potter films the double doors has a portcullis which is used to seal off the Entrance Hall.
