The theme for last Saturday's drive-in was horror.

The movie that received the most votes was the thriller Stay Alive.

To add to the spook factor, the drive-in was held at the now-defunct Bidadari cemetery along Upper Serangoon Road.

It was the second time MovieMob had screened a movie there.

"The last time we organised a screening here was during Halloween last year. But it was raining so heavily that we had to cancel the event and turn the cars away," said Mr Choo.

On Saturday, however,the clear skies made it perfect for an outdoor movie.

When The New Paper on Sunday arrived at the site at 6.30pm, the front row nearest to the screen was already fully occupied by cars.

It is common to see moviegoers stretch out on mats to enjoy the show.

In front of the inflatable screen, viewers were spreading out their mats.

Mr Wilson Chua, 40, who works in sales, his wife and two daughters were among those who were making themselves comfortable on the mats the organisers provided.

Regulars at the Movie Mob drive-ins, they arrived armed with pillows, snacks and drinks.

To get a good view of the screen from their car,Mr Spencer Seah, 27, an IT advisor and his girlfriend, Miss Jolene Heng, in her 20s, drove in an hour earlier.

It was their second time attending Movie Mob's drive-in.

"The voting system is good. It gives us a chance to vote for what we want to see instead of them just choosing a movie for us," said Miss Heng, an auditor.

Most said the idea of a drive-in was novel, and the fact that there was no entry fee was a bonus.

Indeed, the slogan for Movie Mob's Facebook group was 'The best things in life are (often) free'.

And its organisers are happy for it to stay that way.

"We started it as a fun and casual thing to be enjoyed by everyone. We also would not want to charge a fee and be held liable if the event falls through," explained Mr Choo.

He said that organising the event costs between $20,000 and $30,000, and is sponsored by companies such as Nissan and Epson.

The organisers had to stop screening movies in November and December last year because of the monsoon season.

Drive-ins started again only in January this year. Approximately 140 cars turned up for last Saturday's session, but Mr Caine Teo, one of Movie Mob's organisers, had expected more.

"It might be because we are screening a horror movie which is not so audience friendly."he said.

"We'll probably stick to blockbusters next time."
