This is a list of movies that I love in which the movie would have been nothing without the cars.
First up The Fast and The Furious - A great movie. Fast paced and entertaining. Worth watching again and again. The cars are definitely the stars in this movie. Vin Diesel and Paul Walker do a great job with a mediocre script and Michelle Rodriguez gives this movie the spice it needs to make this an all around great movie.
2 Fast 2 Furious - An enjoyable movie. Although Paul Walker returns in this installment of the series, I think it should be looked upon not as a sequel but as a stand alone movie. Tyrese is a nice addition to this movie as he is the much needed male sex appeal and can drive with the best of them. Once again the movie's stars are actually the hot cars. Ludacris adds a nice hint of comedic acting as a supportive role. Eva Mendes adds the latin spice to this movie. Miami is also a brilliant costar to the cars.
The Fast and The Furious: Tokyo Drift - I personally love this movie. The cars are great and the drifting scene is not widely known here in the states. The cinematography is gorgeous and the editing is brilliant. Although the main character in this installment is different from the rest of the series, I definitely think this movie is worth watching. Bow Wow does a great job as the loud mouthed best friend of the main character.
Fast and Furious - Probably one of the best car movies I have seen. Loved the script and the cinematography of this installment in the series.
Gone In 60 Seconds - Although this was a remake, I liked it just the same. The cars were definitely the stars in this movie. Nickolas Cage and Angelina Jolie are steamy in this remake.
Torque - Although this movie is not based around cars per say It is based around some pretty hot motorcycles. The script is crap but the bikes and action make up for it.
Redline - Another crappy script but the cars make up for it.
Deathrace - A brilliant combination of cars, action, and plot. Gritty but enjoyable.
Although I am sure that there are others this is all I can think of right now.
