A bit of clarification about coursework is here! Rejoice (or despair, but not too much, if you need to revisit your work)!
Teaser posters should highlight either:
1) the star
2) the genre
3) the basic premise
There will NOT be a certificate, as it will be unlikely to have been issued at this stage.
You might add a rough release date (eg Winter 2014).
As far as text is concerned, check out the teaser for 'Misery' (1990), which featured the following text: 'This Christmas There Will Be...Misery. From Colombia Pictures.' There was also some small print beneath.
At the other end of the scale, simple imagery told the tale in the teaser for 'Batman', which featured the iconic shape of the mask and simply the word: 'Returns'.
