The formula for calculating the Top Rated 250 Titles gives a true Bayesian estimate:

weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C where:

•R = average for the movie (mean) = (Rating)
•v = number of votes for the movie = (votes)
•m = minimum votes required to be listed in the Top 250 (currently 25000)
•C = the mean vote across the whole report (currently 7.1)

for the Top 250, only votes from regular voters are considered.

Since a large portion of the votes are likely to be from new or infrequent voters, Vishwaroopam (2013) would probably not meet the 25,000 vote threshold for including it in the IMDb Top 250. Even if all of the votes were from regular users, the weighted rating (WR) would only be 8.3. This would give it a rank of around 75.
