As a Data Analyst for a movie production company, you are tasked with cleaning a dataset of movies before importing them into Tableau. Below is a partial screenshot of the first $20$ movies from the IMDB Top $250$ Movies dataset. Start by looking over the screenshot to understand the columns and what the data represents about each film. You will find that while some of the data below is ready to analyze in Tableau, other columns have data that need to be reformatted before an analysis. After you are finished looking over the dataset, proceed to the question below.

Question: Of the eleven columns that are included in the dataset, four columns will need to be reformatted before proceeding to an analysis in Tableau. Which four columns need to be reformatted, AND how would you reformat the data in each of the four columns so they are ready for analysis? Use complete sentences in your response. Tip: It may be helpful to test out a few rows of data in Excel and Tableau before answering.
