When you italicize a word or a phrase, it gets noticed. However, italics (typeface that slants to the right) are a bit understated and do not attract the same attention as say, bold or underline. When to use italics? There are certain style rules to remember. However, italics are popularly used to call attention to certain words in a block of text. When you think about it if all the words looked the same, reading would be a rather boring affair. One thing to remember for any typeface is not to go overboard. If every other word is italics, it loses its effect and becomes less 'special.'
Like so many rules in the English language, rules for italicization vary. Often italics and underline can be used interchangeably. There are some style guides that prefer the use of underlining over the use of italics (and vice versa).
Here are, though, some rules of what to italicize. However, do keep in mind that for some of these categories below underlining is also possible.

As we have discussed italics and underline can both be used for titles of major works. There are certain style guides that require underlining for titles, such as the MLA.
I have never seen the movie Titanic.
We have to read two plays by Shakespeare: Hamlet and Macbeth.
Also, sometimes italics can be difficult to read, so some recommend underlining to really emphasize certain words and phrases.
