With the new Jurassic Park movie generating a lot of buzz, the one that started it all is currently available as a 99c digital rental (in HD or SD) at Amazon Instant Video (AIV). This runs for 2 hours and 8 minutes. You can play it on a device capable of handling AIV as usual. Once you rent it, you have 30 days to watch it. Once you start watching it, you have 24 hours to watch as many times as you please. If you don’t start watching within 30 days, unfortunately you do not get a refund, so don’t rent unless you are certain you are going to have the time to watch it.

On the other hand, if you are feeling Jurassic World hype, Amazon has a triple bundle for $30 that gets you $15 in Fandango to watch Jurassic World, a pre-order of the Jurassic World BluRay Combo Pack, and the original Digital HD copy of the original 1993 movie.

For a limited time, Amazon Instant Video is offering a digital rental of the St Vincent starring Bill Murray for 99 cents. You have 30 days to start watching it. Once you start watching it, you have 48 hours to watch it as many times as you like. If you don’t watch it within 30 days of rental date, you don’t get a refund. If you have any digital credits (eg if you are a Prime member and selected slow shipping on previous offers) you may end up renting it for free (if you have credit in your account). I do not know when the offers ends but these are typically limited time promotions.

The critically-acclaimed movie “Unbroken” is now available for rental in HD for 99 cents at a number of high profile digital movie rental streamers including Amazon Instant Video and Vudu (in what they call “HDX”) and M-Go.

If you have any store credits or promotional bonuses at any of those places, you can watch it for free. For example, if you are a Prime member and you chose slower shipping (instead of 2-day), you get a $1 credit added to your account that can be used on Video or MP3s or e-books.

ORIGINAL POST (EXPIRED OFFER)
If you plan to watch a lot of movies in the next 30 days or so, Vudu has a 99-cent movie rental promotion, with 100 different movies of diverse interest participating. Obviously they don’t have the latest, you can’t possibly expect to find Guardians of the Galaxy for a 99c rental, but they have some well-known movies, such as American Psycho, Stomp the Yard, Ghost, Flatliners, Point Blank, Top Gun, Kill Team and more.

I don’t know when this promotion expires. Once you rent a movie online, you have 30 days to start watching it and once you start watching it, you typically have 24-48 hours to finish it (varies by movie). If you don’t start watching it within 30 days, you lose the chance to watch it (but sadly they don’t give you a refund).

Speaking of Vudu, they are offering the first episode of season one for FREE from a select few new TV series [updated link with October 2016 shows]. The selection changes over time as new shows come in. The free pilots are available only for a limited time, but once you get them, you can watch them forever.
